Deck ID in object records
When you specify the name, and it is not a sequence symbol, it has a special significance. The assembler uses the name value to generate the deck ID in object records. The deck ID is placed in the object records starting at byte 73. It is not generated for records produced by the PUNCH and REPRO instructions. The name value does not need to be on the first TITLE instruction.
The name is not defined as a symbol, so it can be used in the name entry of any other statement in the same source module, provided it is a valid ordinary symbol.
GOFF Assembler Option (z/OS® and CMS): When you specify the GOFF assembler option the deck ID is not generated.
