Reformatting FORTRAN Programs
Believe it or not, there are still folks out there who
are committed to the FORTRAN programming language. It is not
my intention to start a religious war over the merits or
demerits of any particular language, but to offer a tool
which attempts to provide a structured look to a FORTRAN program
for easier reading and understanding of code.
What It Is
If you use FORTRAN but don't like having to enforce a particular
indenting style in your source code, you can run this program on your
to provide indentation and to fix line-breaking over continuation
lines. I'm afraid that the program makes most of the formatting
decisions for you, and there is almost nothing that is customizable
a la GNU's indent program for C. It sounds like
fascism, but I wrote this thing to reformat a bunch of programs we
had obtained, and I needed something ``quick and dirty'' to
to provide nice listings. When running in listing mode, fpret
can also provide an index of subroutines, entry points,
functions, and programs.
The program fpret is written in the C language,
so you will need a C compiler. If you want to produce
a program listing, you will also need TeX, Donald Knuth's excellent
typesetting program. I have only compiled this program on Sun systems
under SunOS4.1.x, so your mileage may vary.
The following link will download a shar (SHell ARchive) file
which contains instructions for compiling and running fpret,
as well as the program source file itself. You must switch your WWW
browser into a mode which will save the downloaded information as a file
before activating the link. Once downloaded, the files in the archive
may be unpacked with the following command (assuming a UNIX OS):
BEWARE! The newer test version will allow some Fortran90
constructs, and attempts to fix a bug in the previous version which arises
when a FORTRAN comment comes between a statement and a continuation line.
I have not fully tested this version (as if I really even attempted
to "fully test" the first version -- but at least I have some experience with
If you have suggestions about the formatting that fpret
produces, or features, bugs, etc., you wish to report, then
