SOME BASIC
COMMANDS
You have used one BASIC command a number of
times—PRINT. Whenever the computer sees the
word PRINT, it will print (display on the screen)
the information that follows the word PRINT. If
the information begins and ends with quotation
marks ("THISPROGRAM WILL"), the computer
prints the information exactly as you typed it. If
the information is not enclosed in quotation
marks, the computer will assume that you are
using the word or letter following the PRINT
command to represent a number, and the com
puter will print that number.
You also used a command called INPUT in this
program. The INPUT command causes the com
puter to print a question mark, and the com
puter then waits for you to provide some type of
information. Line 50 and line 70 of the program
use INPUT commands to store the numbers to
be multiplied. You use INPUT commands in a
program in which there is information that you
will want to change every time you run it.
