So I must be RM> confused about something. circular arrays are slow as they require indexing which is slow. a shift register should be faster and IMO cleaner code. when the first pass coding is done and working, we can benchmark two versions and see. as for the separator, we set it to '' initially and only set it to '--' when we know we first need it. that should be simple logic as we discussed. sure if A=B=0 then there is no separator so we just keep it at ''. 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
