CICS® Transaction Server for z/OS®, Version 3 Release 1 provides
a range of new functions that enable you to enhance your existing applications,
and to construct new applications, using contemporary programming languages,
constructs, and tools.
Enhanced inter-program data transfer: channels as modern-day COMMAREAs
Traditionally, CICS programs have used communication areas (COMMAREAs)
to exchange data. In CICS Transaction Server for z/OS, Version 3 Release 1, channels and containers provide
an improved method of transferring data between programs, in amounts that
far exceed the 32KB limit that applies to COMMAREAs.
OPENAPI Support
CICS extends
the use of Open Transaction Environment (OTE) functionality by providing support
for OPENAPI application programs. Prior to this, OPENAPI function was available
only to task related user exits (TRUEs).
XPLink Support
Extra Performance Linkage, (from here on it is abbreviated to XPLink),
is a z/OS feature
which provides high performance subroutine call and return mechanisms. This
results in short and highly optimized execution path lengths.
