 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...

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


 This works on my machine, hope it helps.
