Threadsafe command list

Not all EXEC CICS® commands are threadsafe, and issuing any of the non-threadsafe commands causes CICS to use the QR TCB to ensure serialization. The commands that are threadsafe are indicated in the command syntax diagrams in this programming reference with the statement: "This command is threadsafe", and are listed here. See CICS threadsafe commands in the API for more guidance on the use of threadsafe commands and see the CICS Application Programming Guide for information about writing threadsafe application programs.
