Can someone direct me to > where can I get more information about the format of unformatted (no > pun intended!) files? Thanks for the help. I would just write a small fortran function to read in the file, then link the fortran funtion into your C program. You will have to worry about differences in argument passing, but that seems much easier than decoding the fortran file format. Why re-invent the wheel? -greg. ---- Greg Stiehl (gstiehl@convex.com) Graphics Software Convex Computer Corp.
