Introduction The Epson IX-86 printer combines low price with the high quality and advanced features formerly available only on more expensive printers. LX-86 Features In addition to the high performance and reliability you’ve come to expect from Epson printers, the LX-86 offers: l Draft mode for quick printing of ordinary work l Near Letter Quali[...]

About This Manual We’re not going to waste your time with unnecessary information, but we won’t neglect anything you need to know about the Ix-86 and its many features. You can read as much or as little of this manual as you wish. If you have used printers before and have a specific program that you want to use with the LX-86, a quick reading o[...]

Chapter 1 Setting Up Your LX-86 Printer Setting up your LX-86 printer is a simple matter of attaching two parts, putting in the ribbon and paper, and connecting the printer to your computer. This chapter will have you printing a test pattern within fifteen to twenty minutes and doing more complicated work not long after. Printer Parts First, see th[...]

In addition to the items in the box, you need a cable and possibly an interface board. The cable connects the printer to your computer, and the interface board is necessary only for those computers that can’t use the LX-86’s Centronics ® paralle1 interface. Your computer manual or your dealer will tell you which cable you need and whether or n[...]

Figure 1-2. Paper feed knob installation Ribbon Installation The LX-86 printer uses a continuous-loop, inked fabric ribbon, which is enclosed in a cassette that makes ribbon installation and replacement a clean and easy job. The parts of this cassette are labelled in Figure l-3. Ribbon Knob Pi n Pin Figure l-3. Ribbon cassette 5[...]

To install the ribbon, first open the lid at the front of the LX-86 so that you can see the print head assembly shown in Figure l-4. Move the assembly by hand to the center of the printer so that the other parts of the printer will not get in your way. Also be sure that the paper bail is against the black roller so it too will not be in your way. N[...]

Then hold the ribbon cassette so that the small knob is on top and the exposed section of ribbon is away from you. Insert the cassette in its holder by first sliding the pins at the back of the ribbon cassette under the small hooks on the holder. (See Figure l-5.) Then lower the front of the cassette so that the exposed section of ribbon can fit be[...]

Now turn the knob on the cassette in the direction of the arrow to tighten the ribbon. As you turn the knob, see that the ribbon slips down into its proper place between the print head nose and the silver ribbon guide (Figure l-6). If it doesn’t, guide it with a pen or a pencil. Figure l-6. Ribbon placement Ribbon Replacement When your printing b[...]

Paper Loading Now put a sheet of paper in your LX-86 so you can test it. Figure l-7 shows the names of the parts that you need to know. Friction lever Figure l-7. LX-86 ready for paper loading 9[...]

See that the printer is turned off, open the front lid, and push the friction lever back and the paper bail forward. Then move the print head by hand to the center of the printer and feed the paper into the paper slot in the top of the printer. When the paper will not go any farther, turn the paper feed knob to advance it as you would with a typewr[...]

There are three buttons and four indicator lights on the control panel. Lights l The POWER light glows green when the power is on. l The READY light glows green when the printer is ready to accept data. This light flickers somewhat during printing. • The PAPER OUT light glows red to indicate that the printer is out of paper or the paper is loaded[...]

Test Pattern Now you’ll see your Lx-86 print something even though it’s not connected to a computer yet. Make sure that your printer has paper in it and that the power switch is off. Now, hold down the LINE FEED button on the control panel while you turn the printer on with the power switch. The Lx-86 will begin printing all the letters, number[...]

Connecting the LX-86 to Your Computer Now that the test pattern has shown that your printer is working well, it’s time to hook it up to your computer. It is best to have both the printer and the computer turned off when you do this. Remember that each computer system has its own way of com- municating with a printer. If your computer expects to c[...]

Next connect the other end of the printer cable to your computer. On most computers you can easily find the correct connector for the printer cable, but if you are not sure, consult your computer manual or your dealer. First Printing Exercise Now it is time to see something more interesting than the test pattern from your LX-86 printer. Your next s[...]

Chapter 2 SelecType The LX-86’s SelecType feature can produce four special typestyles: This is emphasized printing. This i s in the double-strike mode . This is condensed printing. This is in the elite mode. SelecType Operation Using SelecType is easy. You turn on SelecType and select a type- style, then turn off SelecType and print. Note: Each b[...]

Note: If the printer beeps twice before you release the buttons, you have pressed the FORM FEED button before the OFF LINE button instead of at the same time and the LX-86 is in the NLQ mode. Press the OFF LINE button to put the printer back on line and press the DRAFT button if you do not want NLQ. Then press both the OFF LINE and FORM FEED button[...]

After turning on SelecType, follow these three steps to select a typestyle: 1. Find the typestyle you want in Table 2-1. Table 2-l. SelecType modes Mode Typestyle or Function 1 Emphasized ABCDEFGHIJKLMnopqrstuvwxyz 2 Double&trike ABCDEFGHIJKLMnopqrstuvwxyz 3 condensed ABCDEFGHIJKLMnopqrstuvwxyz 4 Elite ABCDEFGHIJKLMnopqrstuvwxyz 2. Press the OF[...]

Now, run the program by typing RUN and pressing RETURN, or print your file or document by following the printing instructions of your software. The LX-86 will print your example in standard single- strike printing, as shown below: This is an exampl e of LX printing . Now that you have created a sample, follow these steps to print it in condensed mo[...]

SelecType Tips Once you have learned the simple technique for controlling print styles with SelecType, you can use it whenever you wish. You should be aware of a few restrictions, however. l SelecType is designed to control the printing of an entire file or document, not an individual line or word. l If you are using the NLQ mode, remember that the[...]

Chapter 3 Elements of Dot Matrix Printing This chapter is for those of you who want to know something about how your printer works. It’s a simple, non-technical explana- tion of the basics of dot matrix printing that will help you understand some of the later chapters. The Print Head The IX-86 uses a print head with nine pins or wires mounted ver[...]

Bidirectional Printing In nearly all of our discussions in this manual, we describe the action of the LX-86 print head as moving from left to right, as a typewriter does. During its normal operation while printing in the draft mode, however, the LX-86 prints bidirectionally. That is, the print head goes from left to right only on every other line. [...]

[...]

In Figure 3-3 there is a grid of lines behind the pica characters so that you can more easily see how they are designed. As you look at these characters you can see three rules that govern their design: the column on the right side is always left blank so that there will be spaces between the characters on a line; no character uses both the top and[...]

The panel buttons make it especially easy to change from draft to NLQ, but you can also select and cancel the NLQ mode with a software command which you can find in Chapter 5. 25[...]

Chapter 4 Printer Control Codes The LX-86 printer is easy to use, especially with commercial soft- ware that has print control features. This chapter explains some of the basics of printer control and communications to help you understand how a computer communicates with your printer. This information should also help you understand the terms used [...]

Computer and printer interaction would be terribly confusing if different kinds of computers and printers used different numbers for the same letter of the alphabet. Therefore, most manufacturers of computers, printers, and software use the American Standard Code for Information Interchange, usually referred to as ASCII (pro- nounced ASK-Key). The [...]

Printer Codes To take advantage of the many print features of the IX-86, you can use a software program that sends the correct codes or you can use another method to send codes. It’s not possible to be as precise and specific as we would like in the rest of this chapter because the IX-86 works with so many different applications programs and com-[...]

l The ESCape and control keys on your computer’s keyboard. With this system you send the ESCape code by pressing the ESCape key and a carriage return by pressing the control key and the M at the same time. (See Appendix B or the Quick Reference Card for the control key codes.) Embedded codes A program that uses embedded codes usually has its own [...]

If your word processing program allows inserted codes, it will probably do standard printing without such codes. It is only for special features that you will need to use inserted codes. For example, if you want to have headings in wide bold printing (called double-width emphasized), you would probably have to use inserted codes. For the program we[...]

Chapter 5 IX-86 Features Beginning with this chapter we describe many of the printing fea- tures of the LX-86. Although we include programs that demonstrate these features, you don’t have to be a programmer to learn about the features from these chapters. How much of the rest of this manual you use depends upon your expertise, your interest, and [...]

If you don’t want to do the exercises in BASIC, you don’t have to. Many users are quite happy with their printers without ever learning any more about them than how to turn them on and off and how to load paper. Therefore, you shouldn’t be intimidated by the informa- tion in this manual. In most cases the software that you use for word proces[...]

Now run the program. You should get the results you see below, 10 pica characters per inch. ABCDEFGHIJKLMNOPQTRSTUVWXYZ[]ˆ_`abcdefgh i Changing Pitches Now you can try other pitches. As we explained in Chapter 3, the IX-86 uses the same pattern of dots for pica, elite, and condensed characters, but it changes the horizontal spaces between the dot[...]

To avoid having one program interfere with the printing modes of another, you can cancel a mode one of two ways: l With a specific cancelling code, such as the ESCape “P” that we used above to cancel elite. Each mode has a cancelling code, which you can find in the discussion of the code and in Appendix B. Pica is an exception to this rule. To [...]

In fact, if you need even more than the 132 characters per line that condensed gives you, you can combine elite and condensed for a mode we call condensed elite. It is not really another pitch, because the size of the characters is the same as in the condensed mode; only the space between the characters is reduced. You can see this mode, which allo[...]

All the modes demonstrated in this chapter are compared in Table 5-l. Table 5-1, Summary of LX-86 pitches Print sample CPI Codes on oft 1 inch Near Letter Qualit y 10.0 0 ESC "x" 1 ESC "x" 0 Pica prin t 10.00 ESC "P" ESC "M" Elite prin t 12.00 ESC "M" ESC "P" Condensed print 17.16 ESC &quo[...]

Chapter 6 Print Enhancements and Special Characters Now that you have seen how you can change the pitch of your IX-86 printing, we can show you many more ways to vary and enhance your printing. So that you won’t have to type in dozens of programs to try all the features, we give you just one master program that can demonstrate any feature. Bold M[...]

Emphasized works only in draft pica and NLQ modes. In elite and condensed the dots are already so close together that even with the reduced print speed, the LX-86 cannot fire, retract, and again fire the pins quickly enough to print overlapping dots. You do sacrifice some print speed and ribbon life with emphasized, because the print head slows dow[...]

You should get the following printout when you run this program and type “E” and “emphasized” in answer to the questions. This sample U ses ESCape E to produce emphasized printing . The code to turn off emphasized is ESCape “F”. Double-strike The other bold mode on the LX-86 is double-strike. For this mode the printer prints each line, [...]

Double-width Mode Perhaps the most dramatic mode on the LX-86 is double-width. It produces extra-wide characters that are good for titles and headings. For this mode, the dot pattern of each character is expanded and a duplicate set of dots is printed one dot to the right. You can see the difference between pica and double-width pica in Figure 6-3.[...]

Mode Combinations You can combine nearly all of the print modes on the LX-86. Indeed, your Ix-86 printer can print such complicated combina- tions as double-strike emphasized double-width underlined italic subscript, although we’re not sure that you would ever want to use such a combination. The point is, however, that the LX-86 has the ability t[...]

Standard Pica Prin t Italic Pica Prin t Figure 6-4. Italic and pica The code to turn italic mode on is ESCape “4”. Try it in the master program if you wish. When you use this code in the master program, enter “4” in answer to the first question just as if it were a letter of the alphabet instead of a number. ESCape “5” turns off italic [...]

This uses the underline mode. Figure 6-5. The underline mode As shown in Figure 6-5, the underline mode is continuous, but some word processing and other applications programs produce an underline that leaves spaces between characters as demonstrated in the printout below. This uses the under-line character If your software prints this type of unde[...]

For any combination,. just add up the values of each of the modes you want and use the total as the number after ESCape “!“. For example, to calculate the code for double-width italic underlined pica, add the following numbers together: underline 128 italic 64 double-width 32 pica 0 224 To print this combination, therefore, you use ESCape "[...]

Indeed, Master Select is such a powerful feature that it may occa- sionally be more powerful than you want it to be. Because it controls eight different modes, a Master Select code will cancel any of those eight that are not selected. For example, suppose that you have a page in elite and want part of it printing in italic. If you use ESCape “!?[...]

If n is 1, the command turns the Character Graphics set on; if n is 0, the command turns that set off. If you prefer to have the Character Graphics set on most of the time, see Appendix D for instructions on using the DIP switches. The Character Graphics set is actually two sets, the standard and the international. The standard set contains only th[...]

You select the character set in one of two ways: with an ESCape code or with a switch in the back of your printer. The ESCape code in BASIC has the following format: LPRINT CHR$(27)“R”CHR$(n ) in which n stands for the appropriate number from the list above. In other words, the BASIC command to select the French character set is LPRINT CHR$(27)[...]

Once you have selected an international character set with [...]

Graphics character set The Lx-86 printer’s Read Only Memory (ROM) also contains the 32 graphics characters that you see in Figure 6-6. Figure 6-6. Special graphics characters Undoubtedly you can think of uses for many of the shapes and symbols available in this set, and you can combine the line graphics characters (the ones on the first row) to f[...]

The next printout shows the characters in emphasized double- width pica: Because normal line spacing leaves space between the lines of graphics characters just as it does between lines of text, you must change the line spacing when you combine line graphics characters to form boxes or other figures. For most programs ESCape “1” gives you the be[...]

Chapter 7 Page Formatting Although the LX-86 printer has many sophisticated commands to set margins, line spacing, and horizontal and vertical tabs, we won’t take up your time with extensive discussions of these because most of these functions are taken care of by applications programs. This chap- ter merely describes a few commands that the aver[...]

You should be aware that a few applications programs reset the printer before each document or file they print. These programs will, of course, cancel your new margin settings. See Chapter 2 to find out how to test for a reset code in your program. The maximum right margins on the LX-86 printer are 80 in pica, 96 in elite, 137 in condensed, and 160[...]

Skip Over Perforation If you are using continuous pin-feed paper for printing program listings or other material not controlled by an applications program, you may find that the LX-86 prints right over the perforations be- tween pages. The LX-86 has an ESCape code to prevent this: the ESCape “N” command. You send ESCape “N” followed by the [...]

Standard line spacing The default line spacing illustrated in Figure 7-l is the only one you need for almost all printing of text, but in some cases you may want to increase or decrease the space between lines. The LX-86 has several commands to do this. ESCape “0” decreases the line spacin[...]

Paper-Out Sensor Under the platen (the black roller) of your LX-86 printer is a small switch that senses whether or not paper is in the printer. When the end of the paper passes this switch, it sends a signal that sounds the beeper and stops your printing. This saves wear on your print head, ribbon, and platen, but because of the distance between t[...]

Chapter 8 User-Defined Characters The LX-86 has several hundred different characters stored in its ROM (Read Only Memory). Although this number includes draft, italic, international, character graphics, special graphics, and Near Letter Quality characters, sometimes you would like to have a few more. For those occasions when you need a special char[...]

After you have created your own characters with our programs, certain keys that you seldom use will generate the user-defined char- acters. For example, you will be able to type < to print . Your user-defined characters can be utilitarian or imaginative, any- thing from a scientific symbol to script letters for your initials. Just follow the sim[...]

When you place your dots on this grid, remember that dots cannot go on horizontal lines, but they can go on vertical lines so long as they do not overlap any other dots. As you design your characters, draw the dots as large as you see them in the example on the left in Figure 8-2. If you draw them smaller, you may have overlapping dots with- out re[...]

So that you can see how the program works, we’ll present the steps used to create the symbol for Mercury. First is the grid we used to design the character. 8 7 6 5 4 3 2 1 123456789 Figure 8-3.

Now wait a moment for your computer to calculate the dot pat- terns and your LX-86 to print the new character in two different typestyles. Your printout also gives you nine numbers, which you will use in the next program. You should get the printout you see below: When you get to this point with a character of your own, you see how it looks and whe[...]

The two lines when printed by your own program provide you with a key to the characters your LX-86 will now print. When you press the key for one of the characters in the top row, the printer will print the corresponding character in the bottom row. In the example above, if you type< your LX-86 will print (although your screen will continue to s[...]

When you run this program it prints six characters, then redefines one or more of them and prints them again. As with the draft charac- ters, you use this two-line printout as a guide to the new characters your IX-86 will print. You can use them with an applications prog- ram or a program you write yourself. 70[...]

Chapter 9 Introduction to Dot Graphics The Epson dot graphics mode allows your LX-86 printer to pro- duce pictures, graphs, charts, or almost any other illustrative or crea- tive material you can devise. Instead of using the standard letters, numerals, and symbols stored in the LX-86’s ROM (Read Only Memory), the graphics mode prints dots column [...]

Bookstore Inventory MAGAZINES BEST-SELLERS SCIENCE FICTION ---- - ROMANCE NON-FICTION CLASSICS MYSTERIES WESTERNS If you have a program that produces graphics, all you need to know about Epson dot graphics is how to use the software. If, on the other hand, you wish to do your own programming or merely wish to understand how the LX-86 prints graphic[...]

Print Head The graphics mode on the LX-86 is quite different from the text modes. Instead of sending codes for letters and printing functions, you send codes for dot patterns, one number for each column in a line. Since none of the predefined characters or symbols in the prin- ter’s memory is used, your program controls where each dot is printed.[...]

The LX-86 has several different graphics densities, but we’ll keep things simple by using only one in the first exercises. The code for entering single-density graphics mode is ESCape “K” n l n 2 . In Mi- crosoft BASIC the command is given in this format: LPRINT CHR$(27)“K”CHR$(Nl)CHR$(N2) ; ESCape “K” specifies single-density graphic[...]

To fire more than one pin at the same time, add up the numbers of the pins and send the sum to the printer. With these labels for the pins, you fire the top pin by sending 128. To fire the bottom graphics pin, you send 1. If you want to fire only the top [...]

With this numbering system any combination of the eight pins adds up to a unique decimal number between 0 and 255. Although you use a decimal number, it is, of course, converted to a binary number before it goes to the printer. Now that you know the principles of Epson graphics, we’ll give you two simple exercises, more densities, and then someth[...]

Line 20 begins a loop to produce multiple print lines. Lines 30 and 40 were covered above, but an LPRINT is added to line 50 to pro- duce a line feed after line 40. Lines 60 and 70 are like lines 30 and 40 except that lint! 70 uses a reversal of the patterns in line 40. As the loop is executed, the program prints lines 40 and 70 alternately so that[...]

You are familiar with the command format that uses the ESCape code and a letter, but LX-86 graphics commands can also be in the following format: LPRINT CHR$(27)“*“CHR$(M)CHR$(N1)CHR$(N2) ; with m being the mode number found in the left column of Table 9-1. As usual, n l and n 2 reserve the number of columns for graphics. The seven modes includ[...]

the maximum number of dots you can reserve on the IX86, then, is: CHR$(27)"Z"CHR$(128)CHR$(7) ; or, in the other format: CHR$(27)"*"CHR$(3)CHR$(l28)CHR$(7) ; which is 128 dots plus 7 times 256 dots, for a total of 1920 dots in one row. Once you have chosen the number of columns you want to use, you can have your program do the c[...]

Design Your Own Graphics In this section we take you through the development of a graphics program. The example is not especially complicated, but it does in- clude the same steps you would use for a more complex figure so that you have the basis for designing graphics on your LX-86. You will plan your figure with dots on graph paper, but before be[...]

Figure 9-4. Arrow design After plotting all the dots as in Figure 9-4, you calculate the num- bers for each pin pattern by dividing the design grid into separate print lines. For the arrow design the grid was divided into three lines, each seven dots high. Then each column was examined and the sums of the pin values determined. This process for the[...]

The numbers for the second and third lines were calculated in the same manner. Once the numbers for the pin patterns are calculated, they go in DATA statements, separated by commas. First we’ll give you the whole program and its printout; then we’ll explain two techniques we have not used before: 90 WIDTH LPRINT 255 100 LPRINT CHR$(27)"1&q[...]

Graphics Programming Tips Now that we’ve shown you how to design your own graphics, we’ll review and emphasize a few elements of graphics programming. As usual, we use MBASIC in the examples, but the principles apply to any programming language. Semicolons and command placement After the graphics command is issued, every number sent to the IX-8[...]

What went wrong? To help you understand the graphics command and avoid some of the more common errors made with it, we’ll examine this program in detail. First look at line 20. ESCape “K” calls for single-density graphics, and the two CHR$ numbers specify 50 columns of dots. Once that command is given, every number sent to the printer is inte[...]

You may also wonder why the program prints not only the differ- ent pin patterns but also the character “J” a number of times. The reason lies in the number of columns you reserved with the graphics command. After the LX-86 receives all the numbers reserved by a graphics command-50 in this case-it leaves the graphics mode and resumes interpreti[...]

Appendix D The DIP Switches Several tiny switches called DIP (for Dual In-Line Package) switches are in the back of your LX-86 printer. They control a num- ber of important printer functions. For most uses they can be left as they were set at the factory, but you may want to change some settings. The design of the LX-86 g ives you easy access to th[...]

Always turn the power OFF (with the switch on the right side of the printer) before you change the setting of any of these switches. Any changes made while the power is on will be ignored until you turn the printer off and back on. So set all switches with the power off. In Table D-l we show you the functions of all the switches. Then we explain ea[...]

Switch l-5 controls the paper-end detector. When it is ON, the detector is inactive, causing printing to continue even when the print- er is out of paper. When it is OFF, the printer stops when the end of the paper passes the paper-end detector. Some computer systems ignore the setting of this switch. See Appendix F. Switch l-4 selects the paper le[...]

Appendix E Using the Optional Tractor Unit The optional tractor unit for the LX-86 allows you to use continuous paper with pin feed holes along the sides. The unit is adjustable so that the continuous paper can be any width from 4 to 10 inches. (The LX-86 can also use the LX-80™ tractor unit.) Printer Location When you use the tractor and continu[...]

Figure E-2. Continuous paper without stand Tractor Unit Installation To install the removable tractor unit, first pull the friction lever toward the front of the printer. Then hold the tractor with the gears to the right as shown in Figure E-3. Figure E-3. Tractor placement E-2[...]

In each tractor slot are two pegs that fit into the notches on the tractor fittings. Tilt the tractor back so that the rear notches fit over the rear pegs. Then tilt the unit forward until it clicks into place. That’s all there is to it. Now install the paper separator and pull out the paper guide as shown in Figure E-4. Fit the notches in the bo[...]

When you want to use single sheet paper in your LX-86, you can remove the tractor unit quite easily. Just push back the two tractor release levers shown in Figure E-5, tilt the unit backwards, and lift it up. Figure E-5. Tractor release levers Loading Continuous Paper Once your tractor is installed, you can load continuous paper. See that the print[...]

Figure E-6. Pin feed bolder adjustment Next, open the pin feed covers as shown in Figure E-7 and feed the paper under the paper separator and into the paper slot; push the paper through until it comes up between the ribbon guide and the platen. Figure E-7. Open pin feed cover E-5[...]

Next pull the paper up until the top is above the pin-feed holders. Fit the holes on the left side of the paper over the pins in the left holder and close the cover. Now fit the right side of the paper in the right holder, moving the holder as needed to match the width of the paper. Close the second cover, make sure the paper has no dips or wrinkle[...]

Appendix F Troubleshooting and Advanced Features This appendix approaches troubleshooting from several directions. The first section uses a columnar format to match solutions with problems. Other sections cover beeper error warnings, hexadecimal data dumping, coding and seven-bit solutions, and specific solutions for several popular personal comput[...]

affect your system if possible. You can also POKE the problem codes directly to the printer port. Seven- bit computers cannot use the eighth pin (12 8). If you have a seven-bit computer and any of your graphics dat a numbers are larger than 127, change the design so that all numbers are less than 128. Be sure that no other commands or carriage retu[...]

Paper-out sensor Can’t deactivate paper-out sensor Computer systems that monitor with DIP switch l-5 or ESCape printer cable pin 12 will ignore "8". both ESCape “8” and the setting of switch l-5. These systems will stop the printing when no paper is in contact with the paper-end detector (a small switch located beneath the platen). [...]

The hexadecimal numbers are the codes received by the printer, and the guide section helps you find a certain place in the list of codes. Each character in the guide section corresponds to one of the codes. If the code is for a printable character, that character is printed. If the code is for a non-printable character, such as the ESCape code or t[...]

A hex printout of a program shows you exactly what the printer is receiving, regardless of what the computer is sending. The following test program lets you check to see what codes, if any, are problems for your computer system. 10 FOR X=0 TO 255 20 LPRINT CHR$(X) ; 30 NEXT X Put the printer in data dump mode and then RUN the program. Remember to p[...]

The second approach is to use commercially available software that is specifically designed to overcome these coding problems. Consult your computer dealer or computer publications to see if a program for your computer system is available. The third approach consists of avoiding the software that is chang- ing the codes. On most computers you can s[...]

The printer interface card furnished with the Apple II computer only passes seven bits to the LX-86, which means that you have a 7-bit system. Should you need an 8-bit system, the simplest solution is to purchase a new printer interface card from your computer dealer. Such a card is available for the Apple II. The Apple II uses CHR$(9) to “initia[...]

he 255 is a special number that prevents the computer system from inserting a CR-LF into the line. Unless, of course, there’s one in your program. The extra line feed-CHR$(10)--that accompanies each carriage return--CHR$(13)-- is no problem except when you need to use CHR$(13) in a graphics program. Getting rid of the extra CHR$(10) is rather com[...]
