All of this reminds me of a trick that I witnessed on
a Model 40 running
DOS/360. Some guy wrote a chained CCW set with a TIC back to the
beginning of the list of CCBs that rang the bell on the 1052 operator's
console and locked the keyboard. The din panicked at least one
operator who pulled the "Emergency Stop" big red button.
Typo--not "CCB" but "CCW".
