The words to search for is 'Message Format Serves' or MFS. The ideal is to split an IMS message into four components: the format displayed on the actual device, the format of the data to be mapped to the device format, the format of the message that is sent from the device, and the mapping to the message actually presented to the IMS application.
The idea was to give the programs some degree of isolation from the physical device and therefore be able to support a number of different devices without any specialized coding. This service is performed in the Control Region, so the format library should not be needed in the message processing regions. IIRC, the format library is actually a pair of libraries that can be switched upon command to bring in new or changed formats without an outage.

I got as IMS910.FORMAT(different naming convention) where all the user generated and system sample screens are stored. I was bit curious to know how the screens are called in IMS region, also I tried googling with keyword(IMS DC) but I was not able to fetch any result pertaining to FORMAT. I was looking at the IMS regions JCL if the IMS910.FORMAT would be concatenated to some start up JCL but that was also not found. Apology if this questions are not appropriate to this discussion list. I am just looking out for some Online Manuals which would say more about the IMS DC .
