FSPLIT(1) BSD General Commands Manual FSPLIT(1)NAMEfsplit — split a multi-routine Fortran 77 file into individual files
SYNOPSISfsplit [-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 subprograms has the form blkdtaNNN.f where NNN is three digits
and a file of this name does not already exist. For unnamed main pro‐
grams the name has the form mainNNN.f. If there is an error in classify‐
ing 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 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. 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.
