And the nice thing about them was they sat in the OS on the tty line. So if it was active it recorded EVERYTHING. I've noticed - with I think both PI/Open and UV - that they sometimes record a "cleaned up" version of the character stream. Which is nice on some occasions, but a pain in the neck on others. > > They upgraded comi files with cpl which was a command processing language > that supported variables and decision based branching. > Not really an upgrade, just a new programming language which sat at the input processing level, not the character stream level :-) and yes, I made a fair bit of use of both of them :-) I actually loved COMO as a debugging tool because, combined with FORTRAN's TRACE statement I could track exactly what my programs were doing. Debuggers can be okay, but if your error occurs on the 30th iteration of a loop it can be a pain, or if you need to track back a fair way to find where things start to go wrong ... the ability to just have a trace of the entire execution was great.
