List of CICS transactions
These transactions are supplied with CICS®, except for those that are part of CICS sample programs.
The first table lists in alphabetical order the transactions that are provided with the various sample application programs, and the second table lists in alphabetical order the remaining transactions that are either used internally by CICS or are provided to help terminal operators manage and change CICS system status.
The transactions that have operator interfaces are marked by an asterisk (*). The remainder therefore have no operator interface.
Transaction is the transaction identifier. Program indicates the program, if there is one, that is specified in the supplied transaction definition. CSD group indicates the supplied resource-definition group that contains the transaction definition. For general information about resource definition and the CICS groups, see An overview of resource definition.
