Last updated: Saturday, 15 June 2019CICS® Transaction Server for z/OS®, Version 5 Release 2 has some new SPI commands to control new system resources, and some existing commands have new options, or new values for existing options. Some system programming commands, options, or values are now obsolete because they relate to obsolete CICS functions.
The system programming commands operate on CICS system resources, such as control blocks and tables of resource definitions, and not on user resources, such as data, on which the API operates.
The SPI is also sensitive to the underlying environment in which it is implemented and, as a consequence, compatibility with future releases of CICS cannot be guaranteed.
This section describes the effect on the SPI of the functional changes in CICS, explaining where incompatibilities exist, to enable you to make programming changes where necessary.
Except for the instances given in this section, CICS continues to provide compatibility with future releases, at source and object level, for application programs that use the unaffected SPI commands.
