GW-BASIC User's Guide
INPUT and LINE INPUT statements have built-in PRINT statements. When an INPUT statement
with a quoted string is encountered during program execution, the quoted string is printed
automatically (see the PRINT statement).
The principal difference between the INPUT and LINE INPUT statements is that LINE INPUT
accepts special characters (such as commas) within a string, without requiring double quotation
marks, while the INPUT statement requires double quotation marks.
Example 1:
To find the square of a number:
10 INPUT X
20 PRINT X "SQUARED IS" X^2
30 END
RUN
?
The operator types a number (5) in response to the question mark.
5 SQUARED IS 25
Example 2:
To find the area of a circle when the radius is known:
10 PI=3.14
20 INPUT "WHAT IS THE RADIUS"; R
30 A=PI*R^2
40 PRINT "THE AREA OF THE CIRCLE IS"; A
50 PRINT
60 GOTO 20
RUN
WHAT IS THE RADIUS? 7.4
THE AREA OF THE CIRCLE IS 171.9464
Note that line 20 in the above example makes use of the built-in PRINT statement contained
within INPUT.
