FSPLIT(1)		     General Commands Manual		       FSPLIT(1)

NAME
     fsplit -- split a multi-routine Fortran 77 file into individual files

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

DESCRIPTION
     Fsplit takes as input either a file or standard input containing Fortran 77
     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 sub-
     programs 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.

     -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 written
     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.  Nonstandard 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.

     fsplit can be used with Fortran 77 and older source code.	 It  understands
     neither Fortran 90/95 syntax nor free form source files.
