     Your examples are close but require a little tweaking to function. Try 
the following:
     global for /a:d %x in (*.*) do ren "%x" /s %@upper["%x"]
     global for /a:-d %x in (*.*) do ren "%x" %@lower["%x"]
    The bonus with these is by enclosing the %x variable in quotes, you can 
handle Windows95's longfile names.
