What does IDCAMS stand for?
IDCAMS is an IBM mainframe utility for managing VSAM data sets and Integrated Catalog Facility catalogs.
IBM module names contain a prefix that relates to a component and product. The "IDC" in the IDCAMS utility is the prefix IBM has assigned to Access Method Services (AMS), which is part of DFSMSdfp, a component of DFSMS, which itself is now integrated into z/OS. The "AMS" of IDCAMS is an abbreviation for Access Method Services. I guess that makes the name redundant.
The list of module prefixes and components can be found in the OS/390 (or z/OS) MVS Diagnosis: Reference manual.
