Ah, those were the days... I have retained my faithful VCR and play Blackadder, Fawlty Towers, and Harry Enfield tapes occasionally when in need of some witty light relief :-). Compared to flat screen HD which is what I'm normally viewing the quality is appalling, but it just goes to show that content usually trumps form, even though form is important. Anyway, getting back to Hercules (wasn't that Steptoe's horse?)... I appreciate the contributions from both of you. I understand your reservations, Alistair, and I also see Doc's point about usual suspects. I have been out of the mainframe arena for so long now, I'm not sure how relevant the usual supects still are, but I suspect many people are still using them under modern versions of the OS. At this stage, I'm not sure on what I would be offering or where my focus should be so it is hard to tell whether Hercules would be OK or not. But at least I am now aware of the option (and some possible pitfalls with it) so I am much better informed. Again, thanks to both of you. Pete. -- "I used to write COBOL...now I can do anything."

According to http://cbttape.org/~jmorrison/mvs38j/ : --begin quoted text: MVS 3.8J is the final public domain version of IBM's OS/370 MVS operating system, released in the late 1970s and early 1980s. It runs with 24-bit addressability so it can only address 16MB of virtual storage. It only supports 3 hexadecimal digit I/O addresses. Aside from those limitations, it has quite a lot in common with today's OS/390 and z/OS systems and can still perform useful work. --end quoted text I recall doing a fair amount of work on such machines that kept a goodly amount of commerce moving.

You're quite welcome, from at least one of us, and supplied with the usual admonition of 'pass it along when you can.' DD
