Re: BPCS History -- MIDRANGE-L

Thanks Joe, I've always wondered why the CPR stuff and the OEAMNU stuff
never got finished, it seemed such a great idea!
Of course I knew about the Unix debacle and was even asked to project manage
in Bangalore but said no....
I was at SSA from 1988 to 2000, and it was great in the early years, but the
tragedy is still playing out! Latest is that SSA Europe have decided to
'outsource' professional services!
And the SQL provides me with more performance tuning business creating
indexes.
What will happen to BPCS? There are still plenty of people using it, some
still on V4.05CD (pre-SQL). Very sad though....

cheers,

Clare
