More BDS help wanted

[David Shoat]

       I have an old copy of the CP/M 80 BDS compiler (minus documentation)
       and am a trifle bamboozled about the file handling procedures, as no
       type FILE is defined for file pointers. Could anybody give me a short
       explanation of the file open procedure?

       Thanks.
