6 fsplit - split a multi-routine Fortran file into individual files
7
9 fsplit [ -e efile] ... [ file ]

12 Fsplit takes as input either a file or standard input containing For‐
13 tran source code. It attempts to split the input into separate routine
14 files of the form name.f, where name is the name of the program unit
15 (e.g. function, subroutine, block data or program). The name for
16 unnamed block data subprograms has the form blkdtaNNN.f where NNN is
17 three digits and a file of this name does not already exist. For
18 unnamed main programs the name has the form mainNNN.f. If there is an
19 error in classifying a program unit, or if name.f already exists, the
20 program unit will be put in a file of the form zzzNNN.f where zzzNNN.f
21 does not already exist.
22 Normally each subprogram unit is split into a separate file. When the
24 -e option is used, only the specified subprogram units are split into
25 separate files. E.g.:
26 fsplit -e readit -e doit prog.f
27 will split readit and doit into separate files.

30 If names specified via the -e option are not found, a diagnostic is
31 written to standard error.

37 Fsplit assumes the subprogram name is on the first noncomment line of
38 the subprogram unit. Nonstandard source formats may confuse fsplit.
39 It is hard to use -e for unnamed main programs and block data subpro‐
41 grams since you must predict the created file name.
