Now don't run ?

[Tim Wessman]

Hello,

The reason is because when INPUT(f,"...") is run, the expression you type is EVALUATED. If X=2, and you type X^2-1, on exit the INPUT form evaluates and you get 2^2-1, or 3 as your value for f.

You can either put your expression inside ' ' using the two keys [SHIFT][ ( ) ], or put in " " around your expression.

'X^2-1' or "X^2-1" will both work.

You can modify the program to be like this to avoid needing to do ' ' or " ".

INPUT({{f,[2]}}, ....);
