Wildcards don't work in this context.  Here's a 'work-around' that I use
quite effectively here though:

 -----8<-----
 FailAt 21
 Echo "Checking for New Mail..." NOLINE
 Dir >NIL: In:#?
 IF NOT ERROR
   Echo "New Mail Found on `Date`"
   Echo "Nodelist Processing Started..."
   Echo "Checking for Node Diff ... " NOLINE
   DIR >NIL: In:NODEDIFF.L??
   IF ERROR
     Echo "None Found."
   ELSE
     Echo "New Node Diff Found."
 ... and so on ...
 -----8<-----

That should give you the idea of what to do.  Don't forget to set your
failat high enough to avoid having the script fail on one of the 'dir'
commands and you should probably reset it again at the end of the script.
