DFSMSdfp: Prepare for the removal of TSO copy services commands

- CESTPATH
- CGROUP
- CRECOVER
- CSUSPEND

- XADVANCE
- XCOUPLE
- XDELPAIR
- XEND

Steps to take
Convert existing non-query TSO commands to the
REXX version using the programs provided in SYS1.DGTCLIB (ANTFREXX
for FlashCopy, ANTPREXX for PPRC, ANTXREXX for XRC). Some of the command
keywords are slightly different than the TSO version, and might need
to be modified. For example, for full volume FlashCopy establish,
you might enter the TSO command, as follows:
FCESTABL SDEVN(0F60) TDEVN(0F61)
To
use the REXX interface, you can enter:
ANTFREXX FCESTABLISH SDEVN(0F60) TDEVN(0F61) SRCEXTNA() andTGTEXTNA()
