Commodore Plus 4 - Page 80

This gets more interesting when variables are also used. User input —i
can be displayed, and earlier calculations saved in variables can also
be PRINTed out, or even used in additional calculations.
Examples
TYPE
10R-10 ' 2: N = R 5 —
20 PRINT "RIS ";R;" AND N IS ";N
30 PRINT "BUT R TIMES 2 IS";R*2 __
40 PRINT "AND N MINUS 2 IS";N-2
Normally, after each PRINT statement, the cursor automatically goes
to the beginning of the next line You can override Ihis by putting a
semicolon (:) after the PRINT statement like this —
200 PRINT 'THESE TWO SENTENCE PARTS WILL BE "; —j
210 PRINT "PRINTED ON THE SAME LINE"
■•■,.:,-,,..,: n.tirit- INPUT —*
Format INPUT "optional message variable to be input
The INPUT statement lets you get data from the program user through
the keyboard, and use it in the program. The optional message lets you
tell the user exactly what you are asking for; the message is printed
when the INPUT statement is executed, along with a question mark
Then
the Plus 4 waits for the user to type an answer, followed by press- —
ing the RETURN key The input from the user is placed in a
variable You can either get a string from the user by using a string
variable (AS, for example), or a number by using a numeric variable
The INPUT statement can only be used in program mode
Examples:
TYPE —
10 PRINT "WHAT IS YOUR NAME"; __
20 INPUT AS
30 PRINT "I AM PLEASED TO MEET YOU"; AS;".11
40 INPUT'HOW OLD ARE YOU";AG —
50 PRINT AG; " IS A BIT OLDER THAN I AM."
RUN —
