NUMFILES()
 Determines the maximum number of files you can open simultaneously
------------------------------------------------------------------------------
 Syntax

     NUMFILES() --> nNumber

 Returns

     NUMFILES() returns the maximum number of files you can open
     simultaneously in all active programs.

 Description

     NUMFILES() determines the number of files that can be open
     simultaneously under DOS.  This information corresponds to the FILES=
     setting in the CONFIG.SYS file.  However, it is read from an internal
     DOS table, not this file.  Therefore, the function operates with or
     without CONFIG.SYS, and returns more accurate system information.

 Note

     .  The function cannot determine if an additional operating
        system adaptation (Novell's SHELL.CFG) has been made under a Novell.
        network.  These adaptations are only used for the current network
        drive under Novell.

 Example

     Display the maximum number of files you can open:

     ? NUMFILES()         // e.g. 30
