I really liked MASM and PLUS.
I remember two ERs, ADED$ and SMOQUE$. With the latter I was able to move my print out to
the top of the queue ?
IIRC, with ADED$ you could assign (and lock) a CPU to your program. A silly mistake in my
MASM program ?ate? all three CPUs of the 1100/63. Everything froze, and even on the
console in the computer room response was extremely slow. $! had no immediate effect!
Those were the days! I think I will try to get 2200 running, but I am afraid I forgot
most of it (if not all), it?s been over 20 years.
I had a chance to play with PLUS while I was a student at U. Wisconsin.
It was for an independent study course, using a new EXEC the sysprogs
had written to provide access to the batch job queue.
Managed to crash the 1108 (or maybe it was the 1110) twice in a row
owing to a bug in their EXEC. ;)
Later they adapted (or completely rewrote) it, and had the job queue
displayed on TV screens down in the basement of the Computer Science
building in Madison.
