Re: [U2] [UV] INPUTTRAP Statement

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

ON.ABORT

...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.

HTH,

Bill
