It is most likely that unformatted sequential files are incompatible, though. Did you compare the two files and see any difference? What difference do you see? You may try with a newer libf2c.a I have put into ftp account of getz.physik.rwth-aachen.de in ~/pub/f2c and see if there is any difference. compile using gcc file.c -lf2c -lm -lc --Chris
