Description

The INPUT command displays the prompt <expC> on the screen, or a ":" if none is specified, and then reads any valid expression from the keyboard. The expression is evaluated, and the result is stored in the specified <memvar>. If you want to INPUT a character string, then you must enclose the string in quotes, i.e. '...', "...", or [...]. If you enter an invalid expression then the following message will be displayed:

Syntax error, try again

You must then re-input an answer to the prompt.


Example

input "Replace with what? " to value
Replace with what? PRICE*1.2
