fsplit(1)

NAME
     fsplit - split FORTRAN or RATFOR files

SYNOPSIS
     fsplit options files

DESCRIPTION
     fsplit splits the named file(s) into separate files, with one
     procedure per file.  A procedure includes blockdata, function, main,
     program, and subroutine program segments.  Procedure X is put in file
     X.f, X.r, or (depending on the language option chosen) with the
     following exceptions:

     * main is put in the file MAIN.[efr]

     * unnamed blockdataN segments in the files blockdataN.[efr] where N is
       a unique integer value for each file.

     The following options are available:

     -f        (default) Input files are FORTRAN.

     -r        Input files are RATFOR.

     -e        Input files are EFL.

     -s        Strip FORTRAN input lines to 72 or fewer characters with
               trailing blanks removed.

     -d        Create a subdirectory (inputfile.d) for each input file and
               create the output files within that subdirectory.

NOTES
     The following characters are allowed as name characters in MIPS
     FORTRAN.  If used in subroutine or function names they are also used
     in the file names of the created files.

     * dot (.)

     * underbar (_)

     * dollar ($)

     Comment lines after an end and before the next non-comment line are
     discarded.  Comment lines before the first non-comment line are
     discarded.

     EFL and RATFOR are handled identically except for the output file name
     suffix.

     fsplit does not detect name conflicts between an input file name and
     an output file name, nor does it detect multiple output files with the
     same name.  For example, if two input files each contain a subroutine
     named "NARF", fsplit generates two output files called "NARF.f" and
     the second one overwrites the first.  Use the -d option to avoid this
     problem.
