Actually, VMS will warn you about either of those, because the warning
is not about wildcards but about not having specified which version(s)
of the files should be deleted.  Adding ;* will avoid the warning.

In VMS the program calls a standard expansion routine to get each
relevant filespec one at a time, only if wildcard filespecs are the
goal.  The command:

	$ SEARCH MY_TEXT.DAT *.*

looks for the explicit string *.* in the file MY_TEXT.DAT without
any (misguided) attempt to expand wildcards.
