JA> Of course, splitting on a null string has the same effect. yes, but you don't get why. the first arg to split is ALWAYS a regex, regardless of the delimiters used. the one exception is the special case (documented) of ' ' which is not the same as / /. so splitting on '' is the same as // because the string (or any expression) is converted to a regex by split. uri -- Uri Guttman ------ [email protected] -------- http://www.sysarch.com -- ----- Perl Code Review , Architecture, Development, Training, Support ------ --------- Free Perl Training --- http://perlhunter.com/college.html --------- --------- Gourmet Hot Cocoa Mix ---- http://bestfriendscocoa.com --------- _______________________________________________ Boston-pm mailing list [email protected] http://mail.pm.org/mailman/listinfo/boston-pm
