COBOL Manual for TNS/E Programs (H06.08+, J06.03+)

rerun-file, system-name, units, condition
are handled as comments.
rerun-file-2-phrase

SAME AREA clause
specifies the files that share the same memory during program execution. These files do not
share disk space or tape space.
The SAME AREA clause has different meanings for I-O files (sequential, relative, indexed) than
for sort-merge files.
same-file
is a file-name.
MULTIPLE FILE clause
NOTE: The 1985 COBOL standard classifies the MULTIPLE FILE clause as obsolete, so you
are advised not to use it.
