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.
-
-
- -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.
