This directory contains RENUM, a program which will
renumber a Fortran program so that all statement labels in
each compilation unit are numbered in ascending order. The
program currently generates labels starting with label 10
and increasing in steps of 10, but this can be easily
changed by modifying the LOOKUP routine.

If installed, the program will read the name of the
file which is to be renumbered from the command line. If no
command line is present (e.g., if the task isn't installed,
but was invoked with a RUN command), the user will be
prompted for a filename. An extension of .FTN (or .FOR in
the VMS edition) is assumed if no extention is provided. If
a second filename is provided, it will be used as the output
file name.

Essentially the same program is provided for use on a
VAX/VMS system in the files RENUM.FOR and RENCOM.FOR. The
only changes required to produce the VMS version were to
change the call to GETMCR to a call to LIB$GET_FOREIGN, and
to change the default filename extension to .FOR.

The RENUM program only calls routines which are
provided in the RENUM source file or in the standard system
library, and no overlays are required even with all compiler
error checking enabled, so no special link commands are re-
quired.

To allow a command line to be passed to the program
when run under RSX, the program must be installed with a
prototype command name such as ...REN. At sites using DCL,
the name ...RNM would be preferable, since this wouldn't
conflict with the DCL RENAME command. To do this, an IN-
STALL command such as

INS $RENUM/TASK=...RNM

should be placed in the system startup command file.

To allow a command line to be passed to the program
when run under VMS, the program must be invoked as a foreign
command. To do this, a symbol definition such as

RENUM == "$RENUM"

should be placed in the system login command file.
