Error "ASMA057E Undefined operation code - IDMSC/DFHCSAD" can occur when trying to assemble the IDMSCINT module.
The error "ASMA057E Undefined operation code - IDMSC/DFHCSAD" can occur when trying to re-assemble and re-link the IDMSCINT module.

To resolve this, it may only be necessary to correct spelling in the JCL. Other sites have needed to add a CICSMAC dddef to their SMP/ JCL (ADD DDDEF) and then include it in the SYSLIB DDDEF concatenation for the target and distribution zones. Once the correct MACLIB is indicated, the error should be resolved, and the compile will complete cleanly.
