COBOL Manual for TNS/E Programs (H06.08+, J06.03+)

The SMU consists of these routines. For complete descriptions of these routines, see the CRE
Programmer’s Guide.

These routines operate upon copies of the process-creation messages that establish the execution
environment of the program. Copies of these messages are not saved automatically and must be
requested by a SAVE directive in the main program. For information on the SAVE directive, see
SAVE (page 563).
The SMU routines operate on the ASSIGN, PARAM, and startup messages, which have standard
sets of defined portions.
