Fun! Now you need to write cmsh.

Virtual Machine System Product. I'll have a look thro' my IBM junk at
home this evening, but I don't think I've got much on it.

IBM draw boundaries in different places, but under VM operating system
(CP, Control Program) usually ran CMS Conversational Monitor System - a
bit like a shell, hence my pun above...

The first scripting language for VM/CMS was CMS EXEC. I never used it
but I understand it was awful. Later came EXEC2 - lots of & characters
(I think - or were they % characters?) to identify names, or reserved
words, or something. This was still the official scripting language
when I encountered VM, but I, like everyone else, used REXX.

This has exhausted my memory - I'm off home.
