Issuing IMS commands
When this option is used, the TS enters a wait and can perform no other functions while waiting for the response. If the response is received within three seconds, an automatic switch to the local log occurs.
If the response is not received within three seconds, the short message
Response not available
is displayed on the current screen.
IMS command responses are not recorded in the subsystem log unless a Rule records it, regardless of the user’s IMSRESP= specification.
