The A > 90 is a condition. The print “YOU ARE SMART” is the command given for the
true condition. In the above example, let’s give A the value 80. Would the message be
printed? No, it would not be printed because the condition is false (80 is less than 90).
Let’s try a program to compute the area of a rectangle.
Type:
NEW
10 INPUT “ENTER THE LENGTH”;L press ENTER
20 INPUT “ENTER WIDTH”;W press ENTER
30 LET A=L*W press ENTER
40 PRINT “THE AREA IS”;A press ENTER
50 INPUT “ANOTHER? (Y/N)”;R$ press ENTER
60 IF R$=“Y” THEN 10 press ENTER
70 PRINT “THAT’S ALL FOLKS!” press ENTER
80 END
RUN
This program uses the INPUT statement to get values for numeric variables and prints
a computed result. It then prompts for a string variable and makes the decision to begin
again if the value typed in is a Y.
Here’s another one.
Type:
NEW
10 INPUT “GIVE ME A NUMBER”;A
20 INPUT “AND ANOTHER”;B
30 PRINT “ADD, SUBTRACT, MULTIPLY OR DIVIDE”
40 PRINT “TYPE IN THE FIRST LETTER OF THE”
