They used UNI-KIX and UNI-SPF and a shell that emulated JCL in many ways. SYNCSORT there made the mainframe version look brain dead. What was interesting is that I didn't have the foggiest notion of what the machine architecture was or the instruction set. I was able to debug the problems using various tools and eliminate some long standing bugs.
Even in IBM z series COBOL, other than knowing the current instruction and the appropriate data areas, things that are useful for Assembler programmers aren't that meaningful in most instances for COBOL programmers. Intermodule linkage can be more complex due to the dynamic call options and the way control flow is handled.
