Specifies the name of the master session. The master session
is a logical entity that is used to coordinate session commands and
data consistency across multiple XRC sessions. A master session exists
as long as there is an XRC session coupled to the master session.
The maximum length of the name is eight characters. Do not include
embedded blanks. TSO ignores the leading blanks and the trailing blanks.
TIMEOUT
The TIMEOUT(hh.mm.ss) parameter may be applied with
the XSUSPEND(msession_id) command only after a coupled XRC
session is uncoupled.
VOLUME
Uncouple XRC sessions from the master session by issuing the
VOLUME(ALL) parameter to the master session. You may also use an abbreviated
syntax of V(ALL).
