Post subject:  Simple Openup format parser
I regularly seem to have to parse files stored in openup format (e.g. created from the BBC BASIC OPENUP and OPENOUT commands) and I've had several random routines kicking around, which I used to copy and paste into various different bits of code.

Finally I thought I'd issue them in a general C library (attached). I also included a simple program that will attempt to dump an openup file to stdout (source code and Windows executable); it's not too clever and may get confused if BPUT has been used too much.

I'm sure these routines can be improved, but if you're feeling lazy, you can nick mine.

What do you mean by OPENUP format? OPENIN/OUT/UP impose no structure on the files they open, they are just purely a sequential sequence of bytes. It's up to the program that uses the files to chose to impose a structure on them.

Do you mean PRINT# format? VisualBasic and C functions available here to read and write them.

I meant PRINT#; I just used OPENUP for simplicity. I've actually had the routines kicking around for a few years (at least since I wrote the initial version of ascape) so I just thought I'd publish them.
