Do u have to examine those as fixed strings or as variable strings? Meaning do u know ahead of time which format ur looking at. If u don't know the format ahead of time then u should use the regex. But if u do know the format ahead of time (like it never changes for one application) then u shouldn't use a regex. Using substr will be faster. "xxxN yyyyyyy sssNNN" $s = substr $string, 13, 3; "xxxN yyyNyyy sssNNNN" $s = substr $string, 13, 3; "xxxN yyyNyyy ssssssN" $s = substr $string, 13, 6; #don't know what format $string will be $s = $string =~ m/\S+ \S+ ([a-z])+/i; -- 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
