SCDRPRN

The CICS® transaction specifies the return primary resource name (SCDRPRN) in the RTERMID field of the START command.

When CICS sends SCDRPRN to IMS, it contains the identification of the terminal to which the return reply should be routed. On output from IMS to CICS, IMS sets SCDRPRN to the name of the source LTERM. MFS can also set SCDRPRN. The SCDRPRN value should be saved by CICS and returned to IMS as the TERMID (PRN) on any subsequent replies.
