Compatibility: 2.0+

 Purpose: Sets the number of File Control Blocks (FCBs) that may be opened

          at the same time.

    Uses: You may need to increase this setting when running some very

          old programs that open a lot of files simultaneously and which

          occasionally fail when attempting to open a file.

  Syntax: FCBS=n


        n is the maximum number of File Control Blocks that can be open at

          one time.  n can range from 1 to 255.  The default is 4.

█ŢTECH NotesŮ█

  ■ It's sort of interesting to note that DOS itself uses FCB calls now and

    then.  In the command Dir /C (to display DoubleSpace compression

    ratios), DOS uses fn 11H to obtain file info in order to get a complete

    directory entry, so that it can trace the FAT chain, access the MDFAT,

    and thereby learn the current compression ratio.

    See CVF Layout for related info.
