SUSPEND
Notes:
1 Command is accepted but ignored by CICS/400.
Description
On other CICS platforms, SUSPEND relinquishes control to a task of higher or equal dispatching priority. Control is returned to the task issuing the command as soon as no other task of a higher or equal priority is ready to be processed.
Note:
In CICS/400 this is a no-operation. It is retained for portability with other
CICS platforms.
