CICS Runtime provides a mapset generator to compile BMS macro source files, to produce a physical (binary) file and a symbolic (copybook) file. There is also an option to produce a listing file. During execution, the mapset generator validates the syntax and level of support for each BMS macro statement.

The generated physical (binary) file should be used in the MAPSET configuration file. See “Mapset Configuration File” in CICS Runtime Configuration Files.

The generated symbolic (copybook) file should be included when you compile the CICS/COBOL program which uses the MAP in this MAPSET
