Depending on which directory a user picks his file, the processing routines
will vary. This means I would need to be able to evaluate the path of the
file that was chosen and run the appropriate subroutine. I would also like to
be able to evaluate the filename as well. The problem I am having is that the
GetOpenFilename returns the path and filename together. Ideally I'd like to
break it into two strings to evaluate both of them before proceeding.

Any help appreciated.
