Is there some reason to avoid `//' as delimiters? no. you should // in most cases. you should change to alternate delimiters (for all delimited string like things) when the default delimiter is in the string itself. or in some cases with regexes like with /x (extended mode) it is easier to deal with other delims. and the best choice for alternate delims are paired ones, in particular {}. uri -- Uri Guttman ------ [email protected] -------- http://www.sysarch.com -- ----- Perl Code Review , Architecture, Development, Training, Support ------ --------- Gourmet Hot Cocoa Mix ---- http://bestfriendscocoa.com --------- -- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected] http://learn.perl.org/
