Re: [PLUG] Book: Modern Mainframe Development

[Walt Mankowski via plug <plug@lists.phillylinux.org>]

The interesting thing about that from my point of view is that while I
worked in COBOL (and some other languages) for about 10 years, none of
them were on mainframes. Most of what I know about mainframes is
whatever I picked up working with the actual mainframe programmers
during that time.
