File logical names.

[Sanibel]

I am in the process of converting some Fortran legacy code from OpenVMS into Visual Fortran.
OpenVMS uses logical names to identify files. Using this method you can open a file in Fortran with the logical name
and define the actual file name in a command procedure (Bat file) when you run the program. Using this method you can change the names of any input and output files in the command procedure without having to recompile and relink the source code.
Does anybody know if a similar facility is available using NT bat files and if so how I can implement it.

Thanks

At a guess, it is something to do with symbolic links. That facility is available on VMS and Unix but not on NT. However, what you can do is to have fixed filenames and use the batch file to

1) copy the input files to the specified filename
2) rename the output files to the desired filename
