NETDISK()
 Determines whether a drive is local or resident on the server
------------------------------------------------------------------------------
 Syntax

     NETDISK(<cDrive>) --> lServerDrive

 Argument

     <cDrive>  Designates the drive that is tested in a range from A to
     Z.

 Returns

     NETDISK() returns .T. when the specified drive is a network drive.

 Description

     NETWORK DISK
     This function allows you to determine if a drive in the range of A: to
     Z: is local or remote.  Remote means that a drive is actually resident
     on a file server and that the local device address has been redirected
     through DOS.

 Note

     .  Since this is DOS information, this function works correctly
        with those networks that support DOS.

 Example

     Test all drives to determine if they are local or resident on the
     server:

     FOR I = ASC("A") TO ASC("Z")
        ? NETDISK(CHR(I))
     NEXT I
