;[7.1225] Note: Since (due to a bad design Arnie) OFNLEN holds the byte size in
;the first six bits, and since COBOL depends on a +infinity byte count to tell
;that a file is an ISAM file. This is not a problem with the FDB since the
;byte count is kept in a word by itself. So, if OFNLEN is -1 that means that
;the file's byte size and count is really 34359738367(36). The OFNLEN word is
;transferred whole from system to system by CFS. (See also TCO 7.1059).
