4.2bsd comes with a standard f77 system interface library, libU77.a, which contains calls for date, time, and other system dependent things not defined in the ANSI standard. There is also an ferror() to print relevent error messages after the fashion of perror(). The error message numbers from runtime I/O are documented on the volume 2c section on f77. You should really get 4.2 because a number of bugs were fixed for that release. If you really want to roll your own, read the volume 2a section on f77. It describes the C interface to f77. However, I strongly recommend that you obtain and use libU77 simply for compatability with the Unix community. libU77.a was/is available for 4.1a bsd. Mail a note to me for details.
