Well, the newest IBM COBOL for VSE is called (simply) COBOL/VSE.  I
think it's the VSE equivalent of COBOL/370 for MVS.  Since COBOL/VSE
only recently came out, and it's the first COBOL for VSE to even have
the full COBOL '85 standard (COBOL II did not have intrinsic
functions) I really doubt that we'll be seeing OOCOBOL any time soon!
When I get Windows 95 I'll probably get the Micro Focus OOCOBOL,
still.
Still, from the books I've looked at OOCOBOL is nowhere near as good
as C++.  COBOL just doesn't seem to lend itself to object oriented
programming.
We get a lot of stuff that is really just ported from MVS and the
vendor says "Here's your VSE version".  And, of course, there are bugs
galore...
Hmm, now that sounds interesting.  I'll have to take a look into it.
The thing with mainframe programming is we application programmers
don't have to worry about building the databases.  That's what systems
programmers are for!  :-)
