Because it IS part of the search order. But that really only applies to the
searches using file extensions.  This is not done with the "raw" name
because it resulted in too many false positives with non-rexx programs
(this was actually added at one point, but it had to be backed out).  In
the poster's situation, he's created his files without extensions, so only
the matching case is used.  If he renamed them to have a ".rex" extension,
then there is much less case insensitivity involved.
