ROYSTA,
Change the filename extension to .txt (if necessary). Now do File - Open.
THat will invoke the import wizard. Use "fixed." You can tell it the
extents of the fields. Prn files are usually full of spaces (to get stuff
where it needs to be when printed). You would set up fields of those
spaces, and select "skip." With patience, I think you can probably get it
done.
If you're not sure exactly where the data is, character-wise, open it with
NotePad, or a text editor. There's the Edit program (Start - Run - Edit).
