FUNCTION =
This DSECT describes the CICS region block, which is
used by the CICS inter-region communication facility.
The block is used to control inter-region activity
at a global level, as opposed to controlling the
activity of individual links with other regions.
The conversational TCTTE (hung off the 'ISLINK'
system entry in the TCT) is the block which
controls individual 'conversations' between CICS
and other regions.
The CRB is allocated when the facility is started
up (by the start-up program, DFHCRSP), and freed when
the facility is shut down (via the IS LOGOFF COMMND).
The block contains, amongst other things, argument
lists and other information required to communicate
with the inter-region SVC (DFHIRCP)
