A pretty simple code:
[/quote]do
input input_string$
if returnkey() then cls
loop[quote]
I wanted to make an input that automatically clears after you press enter. Why is it that when you add in the third line, the text becomes large and distorted?
Would you just have to use the SET DISPLAY MODE command to fix this?

Just do this:


Input is what's known as a "blocking" command, which means that DBPro stops everything else that it's doing to focus on this one command, input. So, you don't need

just go straight to
right after the input command.

I seem to remember trying that as my first code but something went wrong, then I tried to over complicate it. I do remember reading that INPUT was a "blocking" code, but didn't know what it mean't. I guess I learned the hard way!
Thanks a lot.

Does the fact that it is a blocking command keep you from using something like this, because it skrews up!

This would be nice for converting uppercase strings to lowercase!

No, that should still work. It would go like this:


Program waits for input from user.

After it gets the input, program takes the input, lowercases it, and stores it in another variable.

Program loops.

Yes, I understand. Technically the program would work, but if you try it, the text becomes distorted and sequences of lines apear under you text.

Well I know the lines are because the input function produces a flashing _ where the user's input goes, and if you have the backdrop off it can end up staying behind printed on the screen. Not sure why it might get distorted though.

Well, that solves the line sequences problem, but creates a new one. Everthing starts blinking with the "flashing _". Also the text isn't actually distorted, it just gets larger, changing the apearance.
