378.0. "Help on TLAs" by BHAJEE::JAERVINEN (Ora, the Old Rural Amateur) Fri Jun 17 1994 06:04

    In a context where I'm not necessarily willing to reveal my ignorance,
    I've come across a couple of terms and TLAs (and even FLAs) I don't
    know (at least in that context):
    
    - SDL: I know SDL as known in DEC - however, in this context it seems to
    be some sort of a design specification language or some such.
    
    - Harel State Charts
    
    - PCTE

378.1Good guesses...QUARRY::reevesJon Reeves, UNIX compiler groupFri Jun 17 1994 12:146
SDL: I think it stands for Structured Design Language; it's from U of Mich,
and has been around for at least 10 years (at least, that's when I encountered
it).

PCTE: I *thought* it was a POSIX-related test suite or environment, but I can't
find anything to support that now; I may just be confusing it with PCTS...
378.2TUXEDO::WRAYJohn Wray, Distributed Processing EngineeringFri Jun 17 1994 12:246
    Isn't PCTE something like "Portable Common Tool Environment"?  A
    standard defining things like how compilers, editors & debuggers
    communicate with one another, with the intent of allowing mixed-vendor
    integrated tool suites.

    Thanks... in the meantime, I even found a book on PCTE. .2 is right -
    it was developed by a (or maybe more) Esprit projects.
    
    Any further info on SDL? Books?
    
378.4SDL info availableRANGER::BRADLEYChuck BradleyFri Feb 17 1995 17:447
re .0
if SDL is really that language from Umich, it almost always appears
in the string SD?/SDL.  if you are still interested I can probably
find the proper name and the professor who pushed it.
dec had a right to use it back about 81, and i would guess it to be
about 10 years old at the time.

378.5psl/psa is not sdlRANGER::BRADLEYChuck BradleyMon Feb 20 1995 09:059
to correct .4, i was thinking of PSL/PSA, problem statement language,
problem statement analyzer, also done at umich in the I.E. dept by 
dan teichrow. it goes back to 1971 and was still an active project
in the eary 80s.  i should have expected more than 1 ??L project
at a time at umich.

so, no further help in the search for SDL.
