- Why can't you use the DIR$ Function? This function accepts a
- filespec mask and returns a string containing a filename or NULL if the file
- does not exist and can be repeatedly polled for all files meeting a wildcard
- filespec.
-
- IF Len(Dir$(FileSpec$)) > 0 THEN
- (stuff to do if the file exists)
- ELSE
- (stuff to do if it ain't there)
- END IF
