UDFILES.WCX is a wcCode app that adds new or updates existing file
records.

Copy UDFILES.WCX to your wc5 (or whatever you named it) directory.
There is a sample batch file named UDFILES.BAT.  This is probabaly
best stored in the wc5\batch directory.  UDFILES.BAT changes to the
wc5 directory and executes wcrun.  Modify this file to suit your
configuration.
