35 LET’S DO SOME ARITHMETIC In the previous section you learned to program the sum of three numbers using the BASIC program. Numbers like 1, 3, 27, 14.3, etc., are called CONST ANTS , n umbers that do not change v alue. The program added and subtr acted the constants 12, 4 and 7. The order that you do addition is unimportant: 6+10 is the same as [...]

36 T ype this : 10 PRINT 3+11/7 pr ess ENTER RUN Is it really e valuated from left to right? Y es, but w as it the ans wer you w ere expecting? If the ans wer came out to 4.57143, the computer first divided 11 b y 7 getting 1.57143 and then it added 3 to the result giving 4.57143. Y ou probably were e xpecting the ans wer to be 2 because 3+11 is 14[...]

37 The computer creates a box in memory and calls it “A”. It puts the number 8 in this box. Now type : 20 LET B=10 pr ess ENTER The computer creates a box called “B” and places 10 into it.

48 EDIT Use the EDIT command when you want to change a statement that has been typed into memory without re-typing the entire line. Just type EDIT and the line number and press the ENTER ke y. The statement will appear on the display . Use the LEFT -ARRO W and RIGHT -ARRO W k eys to mo ve the cursor . Use the DEL ke y to remo ve an unw anted charac[...]

49 PSET This command is used for drawing a specified point on the screen. PSET X, Y (X, Y) is a coordinate of the specified point to be shown. X represents a value of a horizontal position. Y represents a value of a vertical position. Example: 10 CLS 20 PSET 100, 8 RUN The result: a screen pixel at coordinate (100, 8) will be turned on. PRESET This[...]

50 SOUND This is a command to generate a sound note. SOUND consists of two functions: frequency and duration frequency The frequency of the sound in hertz; a value in the range 0 < frequency parameter < 256 duration The number of the system clock ticks so the sound lasts; a value in the range 0 < duration parameter < 256 FOR ... T O ...[...]

51 T ype PRINT SQR (9). (press ENTER ) The answer is 3. Example: Y=9 : X=SQR(Y) : PRINT X pr ess ENTER The answer is 3. In these two examples, 9 is the argument, SQR is the function and 3 is the result.

52 ARITHMETIC FUNCTIONS ABS (X) This giv es the absolute (positive) v alue of the argument. So ABS (-7)=7. Example: PRINT ABS (7-2*4) pr ess ENTER 1 SGN (X) This function will give the value of +1 if X is positive, 0 if X is zero, and -1 if X is negative. So SGN(4.3)=1; SGN(0)=0; SGN(-276)=-1 Example: A=6 pr ess ENTER PRINT SGN (A); SGN (A-A) pr es[...]

53 Example: PRINT RND (19) pr ess ENTER Y ou will get a number between 1 and 19. RND (0) will give y ou a number between 0 and 1. Note :X cannot be negative. Important Note: Fr om now on, the ENTER key sign will be deleted for simplicity . Remember to press the ENTER key after eac h line of entry . STRING FUNCTIONS We can also use functions to act [...]

54 VA L V AL works like STR$ b ut in re verse . It changes a str ing argument into a number . Look at the following short program.

55 Example: 10 A$=“ABCDE” 20 B$=LEFT$ (A$+“FGH”,6) 30 PRINT B$ RUN ABCDEF RIGHT$ (A$,N) This will return a substring but starting from the Nth character from the end and running to the last one - the right-most character in the string A$. Example: 10 A$=“WHY” 20 B$=RIGHT$(A$+“ME”,4) 30 PRINT B$ RUN HYME MID$ (A$,M,N) This function r[...]

56 ASC(A$) The ASC statement will return the ASCII code, a code f or representing alphanumeric information, for the FIRST character of the specified string.
