FSPLIT(1)                  OpenBSD Reference Manual                  FSPLIT(1)

NAME
     fsplit - split a multi-routine Fortran file into individual files

SYNOPSIS
     fsplit [-e efile [...]] [file]

DESCRIPTION
     fsplit takes as input either a file or standard input containing Fortran
     source code.  It attempts to split the input into separate routine files
     of the form name.f, where name is the name of the program unit (e.g.,
     function, subroutine, block data or program).

     The name for unnamed block data subprograms has the form blkdtaNNN.f,
     where NNN is three digits and a file of this name does not already exist.
     For unnamed main programs the name has the form mainNNN.f. If there is an
     error in classifying a program unit, or if name.f already exists, the
     program unit will be put in a file of the form zzzNNN.f, where zzzNNN.f
     does not already exist.

     The options are as follows:

     -e efile
             Normally each subprogram unit is split into a separate file.
             When the -e option is used, only the specified subprogram units
             are split into separate files. e.g.,

                   fsplit -e readit -e doit prog.f

             will split ``readit'' and ``doit'' into separate files.

DIAGNOSTICS
     If names specified via the -e option are not found, a diagnostic is writ-
     ten to standard error.

HISTORY
     The fsplit command appeared in 4.2BSD.

BUGS
     fsplit assumes the subprogram name is on the first noncomment line of the
     subprogram unit.  Non-standard source formats may confuse fsplit.

     It is hard to use -e for unnamed main programs and block data subprograms
     since you must predict the created file name.
