The most fun thing in VM/CMS is REXX. It's an awesome language invented by Mike Colishaw with the express goal of being easy to program above all other considerations. Its PARSE instruction is one of the most powerful things I've ever seen in any language.

REXX was so great it became the standard scripting language for all IBM system products and was incorporated into the OS command line and the text editor, XEDIT. This meant you could have one language that ran commands and programs in any other language, could do anything at the command line (like create machines, etc), and could edit and save text files. Think about that for a second. It was WAAAAY ahead of its time.

Sadly, REXX predated the internet and never had a browser-savvy release. A miscarriage of REXX and OOPS called Object Rexx was also unsuccessful.

But it was an amazing tool for its day!
