A lot a decent info (a rarety) on the /. forum follwing the article.

Bottom line though: Operations staff are NOT systems programmers. One step above tape monkey, and not very far.

Very little JCL required. In our company, in the entire chain of operations staff, about 7 people, on one would be able to read a JES log.

They are not programmers at all. No COBOL. No data awareness.
