Does anyone know how to determine the file descriptor (useful for system calls) that matches a FORTRAN logical unit under UNIX? Thanks, Chris

I needed to do this with UNICOS 5.1.11, semi-quoting from a Crayon: "It's d*mm near impossible." The reason being (at least on UNICOS) that the file descriptor is an array index pointing to a structure within the kernal. (ie: There is isn't a straight-forward mapping between Fortran Unit numbers and system file descriptrors.....) -PWM -- ------------------------------------------------------------------ Peter W.
