Multithreading inDelphi

How would you create threads say for scanning for a keypress and something else. I am working on a SCSI app and need to be able to test and interrupt the test at any time. The SRB_ABORT and SRB_EXEC need to run simultaneously. In other words, start reading a disk, then if I choose, press ESC and stop (SRB_ABORT). Right now, if I start a process (Reads, for example) the process locks me out until it completes, so I can not abort. Code snippets please.

Try adding Application.ProcessMessages to your code at regular intervals (or in a loop if that's what you're using). You can then process key presses, set flags, and drop out if you need to. Far simpler than messing around with threads

If this hadn't helped you, let me know. Application.ProcessMessages brings you on the right way, but there is a lot more to get them responding!

Thanks for the points - don't know if I deserve but you won't hear any complaints (well not from me).
