PATCH Utility

The patch merge program (SYSTEM/PATCH) is a utility program used to merge one or more patch decks into a single patch deck on disk or pack, without changing the original SOURCE file. This disk file can then be used as the input CARD file for an ALGOL, COBOL74, COBOL85, DCALGOL, FORTRAN77, Network Definition Language II (NDLII), Pascal, or RPG compilation among others

The PATCH utility merges all input patch records by sequence number. Only numeric or blank sequence numbers are accepted. The PATCH utility permits resequencing and patching into resequenced areas of a patch.
