Supporting Variable Length Files In many instances, a variable length file has a physical record size much larger than the actual records contained in the file. Previously, if the physical record size exceeded 256 bytes, HP SRC would have had to archive the file even if the actual size of the file's records was fewer than or equal to 256 bytes. HP SRC now allows variable length files to have physical record lengths greater than 256 bytes and still be checked in as NOMASK or NUMMASK (that is, non-archived) files. This allows these files to use many of the other features of HP SRC, such as LISTDIFF and ADDDIFF, while still saving disk space. However, if any of the data records contained in the variable length file exceed 256 bytes, the file will need to be archived. HP SRC also has added support for variable length files with COBOL line numbers and standard line numbers. So if you would like to have your variable length file renumbered upon check out (or COPYREV), use the NUMMASK option.
