Suggestion: Google COBOL 2002 and read a few entries.
Then, come back to this forum and tell us which version of COBOL you're using and which version you're wanting to use. COBOL 85 and COBOL 2002 are not compilers -- they are language specifications, and as such have pretty much zero relevance to a particular operating system platform. IBM does not have a COBOL 85 compiler, never has had one, and probably never will. They have (or have had) Enterprise COBOL for MVS & VM, OS COBOL, VS COBOL II, and a lot of other compilers. But nothing referred to as COBOL 85 or COBOL 2002. And the IBM compilers do not have a one-to-one feature set implementation of a particular language specification; there tends to be some blending. You will find this applies to other COBOL compiler vendors as well -- I don't think anybody implements a pure language specification.
