[Beowulf] COS XMP

Hello Beowulf,
Tantos' COS simulator appears to in fact have a compiler! Here is what I
found in the dump log:

     o$31('CS031 - INVALID DATASET NAME: 'A8)  101('CS101 - BAD CHARACTER

I made a short video on the subject:

What do you think, do I start writing JCL? It looks interactive, do you
suppose I can fetch CS so as to use the ! prompt?
