BTW:  If I can find one of my old CMU tapes and it is still readable - I should have a version from before it was released in PWB or elsewhere.  I know I >>had<< it in one of CMU EE directories but I do not have that online these days.

BTW: Historical note, the reason the errors were in UPPER CASE was because Ted was a MTS hacker and I was a TSS hacker before Unix and that's how MTS and TSS signaled errors.
