 Hmmmm, I *hope* this isn't the routine that you've already tried...

 First set up the control-alt-del trap....

    KEY 16, CHR$(12) + CHR$(83)
    ON KEY(16) GOSUB NoReboot
    KEY(16) ON
    'more program code etc. etc.

 Then when it's needed it goes to...

    PRINT "No WAY! Ya can't break out of this program THAT easy!"

 This works on my machine, hope it helps.
