User input/Text: Difference between revisions

==={{header|Commodore BASIC}}===

When using the prompt feature of the <code>INPUT</code> command, the string literal must be followed by a semicolon and then the string variable, or else a <code>?SYNTAX ERROR</code> will occur. The question mark prompt is always presented with the <code>INPUT</code> command. Any other behavior would have to come from a user-built routine using the <code>GET</code> command.

Also, when a numeric variable is provided for input, the computer will make repeated attempts to obtain valid input from the user until the input can be clearly interpreted as a numeric value.

<lang gwbasic>

10 input "what is a word i should remember";a$

20 print "thank you."

30 input "will you please type the number 75000";nn

40 if nn<>75000 then print "i'm sorry, that's not right.":goto 30

50 print "thank you." print "you provided the following values:"

60 print a$

70 print nn

80 end

</lang>
