According to the RMS manual, the LRL field is meaningful only for sequential files, but it would appear that it corresponds to the field named F$RSIZ on page 67 of the 1978 version of DEC's Files-11 On-Disk Structure documentation, in which case it is the length of all records for fixed-record-length files, and to the length of the longest record for variable-record-length files.
