Changes to system initialization parameters

There is a new system initialization parameter for XPLink Support. The new parameter is MAXXPTCBS.

MAXXPTCBS={5∨number}
Specifies the maximum number of open X8 and X9 TCBs that can exist concurrently in the CICS® region. X8 and X9 are the TCBs that are used to run C and C++ programs which are compiled with the XPLINK compiler option. X8 TCBs are used for programs in CICS key, and X9 mode TCBs are used for programs in user key.

A CICS task is allowed as many X8 and X9 TCBs as it requires, and these TCBs are only kept until program termination
