The PATCH utility uses the following files, which can be file-equated in the file equation section of the input to SYSTEM/PATCH. The internal names for these files can have multiple nodes. If these files are not file-equated, they are assumed to be named CARD, LINE, NEWSOURCE, NEWTAPE, PATCH, PATCHES, SOURCE, and TAPE.
Any files referenced by the option $.DISK, $.DISK $, $.FILE, $.PATCHDECK, or $.INSERT can also be file-equated in the file equation section. The internal names for these files are described as follows. These file names can have only one node; that is, they cannot contain slashes.
