You can't trap the 'break' key, but you can prevent its usage. In UniData it is:


...which is a very finicky task to accomplish in that the command doesn't permanently turn on or off anything, it simply executes a command on a program abort. For us, the command executes the ON.ABORT command again (for the next abort) the routes the user back to the main menu; a very abstract way to get the job done.

I don't think you can use *any* of the chars that are pre-trapped like ctrl-c 
That is, chars that actually make the op-sys wake up and act in immediate mode

If you are trying to *trap* the break so you can see when someone is trying to 
use it, there is another way, although the other way of which I'm thinking 
doesn't *prevent* its use, it just *records* its use.

Maybe you could go into more detail about why you're trying to trap ctrl-c

Subject: [U2] [UV] INPUTTRAP Statement

Has anyone ever used the INPUTTRAP statement in UniVerse BASIC?  I want to be
able to trap a break (Ctrl-c) but I can't seem to get it to work with CHAR(3),
or any other character for that matter.  The UniVerse BASIC Commands
documentation provides no examples on its use.

Anybody done anything like this?  Any sample code you're willing to share?
