What way would you recommend that the IMS option be removed?
Regarding the '6T' LMP key, if you comment out the 6T or do not have a valid LMP key for this IMS option, then you will receive CAS9180E as well as CAS9012A and CAS9013A messages. If you are no longer licensed for the IMS option, then only running CA Easytrieve IMS jobs will invoke the CAS9 messages. If you remove or rename EZTPB37, then the CAS9 messages will stop. The IMS option will not be enabled.
Please note: 6T LMP key is only checked at compilation time, not runtime.
