XREN.EXE - rename invalid directory/file names

Author: Wolfgang Schreiber

XREN is a DOS tool that allows to rename weird directories or 
files on NetWare 386.

   - The best way to do so is by accessing the file/dir from a Mac 
     workstation (Unix might also help).   If these are not available, 
     follow the procedures described below. 

   - Invalid names include names longer than 8.3 characters, invalid 
     characters, weird names (e.g. 'A.B.C' or '.BAK').

   - XREN uses the CLIB Mac/AFP calls to access invalid directory names. 


Procedure:

   - Create a verified backup of your server (hopefully not needed)

   - add the Mac Name Space to the volume in question (if not yet 
     available. Before doing so be sure to have some available (ca. 
     2%) free volume disk space. See your manual for details)
     This is done by 2 commands:
        LOAD MAC
        ADD NAME SPACE MAC TO <volume name>

   - call XREN.EXE  (syntax is displayed when entered without parameters)
     Syntax:   XREN  <NWpath>  <oldname>  <newname>
     e.g.  "XREN  VOL1:TEST  .BAK  XYZ.BAK"      (case sensitive !!!)
   
   - Optional:  Remove the Mac Name Space by running VREPAIR.NLM
