A little bit tricky issue,I have created one input file with ifort(binary file),later this file will be used by program compiled by g77.I am dealing with a lot of numerical computations,so my question here if this can somehow make problems latter?I have created simple file with my porgram(ifort) and with one made by the author of the code(g77),then with od -h compared output and they are equal.

As long as you are building a 32-bit g77 program, and the record lengths do not exceed 1GB, it should work ok. 64-bit g77 cannot read Intel Fortran sequential unformatted files.
