 TRUENAME()
 Standardizes the path designation
------------------------------------------------------------------------------
 Syntax

     TRUENAME(<cPathDesignation>) --> cStandardizedPath

 Argument

     <cPathDesignation>  Designates a path as a standard.  It is assumed
     that it is in accordance with DOS rules.

 Returns

     TRUENAME() returns the standardized path whenever possible.

 Description

     Path designations are made for the drive as well as the path itself,
     with regard to the current position designation.  With TRUENAME(),
     related path designations are changed around so that they relate to the
     root directory of a particular drive.

     The function does not test to see if a path exists.  If the designated
     path is not valid or the specified drive is unavailable, it returns a
     null string.

 Note

     Warning!  Additional information is built into the path of network
     drives. Under PC-LAN/MS-NET, the path contains the
     designation:\\<ServerName>.  Under Novell, \\<ServerName>\ <VolumeName>
     (see Examples).

 Examples

     .  Which complete path corresponds to the current disk drive?

        ? TRUENAME(".")                        // e.g. "C:\TEST1"

     .  Anything valid under DOS is acceptable:

        ? TRUENAME("..\..\TEST1\.\TEST2")      // e.g. "C:\TEST1\TEST2"

     .  In a Novell network, remove tokens 2 and 3, server name, and
        volume name:

        IF NNETWORK()
           cPath   := TRUENAME(cOldPath)
           cToken1   := TOKEN(cPath, ":\", 1)
           cToken2   := TOKEN(cPath, ":\", 2)
           cToken3   := TOKEN(cPath, ":\", 3)
           cPath   := cToken1 + AFTERATNUM(cToken2 + cToken3, cPath)
        ENDIF
