In my (very limited) z/OS experience, COBOL by itself is necessary but not nearly sufficient. COBOL code is used inside a framework of highly proprietary software and system services:
- DB2 (database is builtin to the mainframe)
- GDG (Generation Data Groups, versioned file system)
- ACL (IBM's original access control lists)
- JCL (automation, parameters, logging)
- SyncSort (data sorting, joining)
- various CA Technologies products
- etc!
- the_only_law 6y agoYep this is why I'm also weary of people who suggest to "just learn COBOL" for a job.
- kjs3 6y agoDon't forget CICS (OLTP component). But spot on...a mainframe is an ecosystem, not a language.
- nonesuchluck 6y agoProbably not hard for you to guess that my experience is limited entirely to enterprise batch processing and data warehousing. I've heard of CICS, but only as a nasty rumor.
