IDCAMS is an IBM utility that allows you to create and
manipulate VSAM data sets. It has several commands. You can
use the REPRO command of IDCAMS to copy VSAM and non-VSAM
data sets, VSAM clusters, and alternate indexes.

IDCAMS is the Access Method Services program. You run the
IDCAMS program and supply AMS commands thru SYSIN. (examples
of AMS commands are DELETE, DEFINE, REPRO etc..).
