FILESMAX()
 Specifies the maximum number of files that can be open at one time
------------------------------------------------------------------------------
 Syntax

     FILESMAX() --> nMaxHandles

 Returns

     FILESMAX() returns the maximum number of files that can be open at once.

 Description

     The value set for FILES= within the CONFIG.SYS, and the number of
     available handles, influences the maximum number of files that can be
     open simultaneously.  The maximum number is determined by the smaller of
     the two values respectively.

 Notes

     .  The returned value is subtracted from the handles already
        occupied by the operating system.  This value is usually 5.

     .  This 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

     How many files can be opened in the system?

     ? FILESMAX()            // e.g. 100
