The COPYGROUP statement has the same effect as the COPYGRP statement when either the input or the output data set or both are partitioned format, that is either PDS or PDSEs. The function of a COPYGROUP statement differs from COPYGRP only if both of the data sets are PDSs. COPYGROUP performs a full group copy operation when both data sets are PDSs. By contrast, a COPYGRP statement with two PDSs is the same as a COPY statement with those data sets.

To abbreviate a COPYGROUP statement, use CP. The abbreviation for COPYGRP remains CG.
