In the latter it is a code block which has to be setup for all the potential things u can put in a code block. Like my's, labels, etc. Simply entering a curly bracket costs money. That's why it's best to avoid them unless ur stringing just way too many and's and or's together. -- REMEMBER THE WORLD TRADE CENTER ---=< WTC 911 >=-- "...ne cede malis" 00000100 _______________________________________________ Perl-Win32-Users mailing list Perl-Win32-Users@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
