>I am writing a TP6 program which requires the CTRL+BREAK sequence to be >disabled, as it loads in data tables and manipulates them in real time. >If CTRL+BREAK is pressed then the program bombs out and leaves the tables >in a real mess. > I played around with this problem a few years ago. The solution I came up with was to hook the Ctrl-Break interrupt. I don't remember what it was (I think it was around 24h). The only thing my interrupt was to do was return immediately to its caller. I used this when I had to write a simple program for a teacher of mine (he wanted students to have to enter a password without being able to break of out the program). Hope this helps.
