well, one of my colleagues pointed out a feature of fortran 2003,
which I, being an idiot, have missed. YOu have access='stream'
in f2003, which is all I need. No record separators, just data.
many thanks for all your help and advice.

truncate -4 myfile should get rid of the last four bytes. Maybe
there's a similar efficient way to truncate the start of a file.
This should do it:

All very interesting, but the OP is wanting to lose all the Fortran

The record markers precede and follow each record, and give the

Or, perhaps marginally more efficient:
If you don't mind, I would add fixed buffer processing to your program.
For some really huge files (or any other type of stream) which have
really huge records, reading entire records into memory would get the
box down.

/* convert.c: remove record length fields from Fortran output fi
If your Fortran file has the same word size and enddian-ness as your
C, this simple program convert.c will strip all the record length
fields. I just knocked it up now, no warranty, etc, but it works for
me. Use as a pipe:
$ ls
convert.c test.f
$ gcc -Wall -Werror -ansi -pedantic convert.c

Or, perhaps marginally more efficient:
dd if=oldfile of=newfile bs=4
