[fpc-pascal]Error Trapping w/ ReadKey

Just getting into the "planning" phase of a personal project I'm working on,
and one of the things I'm trying to do is predict where there's going to
need to be some error trapping things in place.  As a part of this I've been
browsing various message boards taking a look at what various people have to
say about the topic.

One of the things that's come up for checking user input is to monitor what
they input via keystroke one char at a time using ReadKey.  If I'm
understanding this correctly, you can then use the case structure to tell
the program what to do when specific keys are pressed.

Just wondering if I'm headed in the right direction with this, or if anyone
has any code examples of ReadKey / case being used to trap per-keystroke
user input
