No, in Perl a variable is global, anywhere, unless there's a my declaration in a surrounding block. I don't think variable scope is your problem.	[reply]

If both are set, of course the value is 0 again -- one of them takes care of increment, one of decrementing. Both add up to 0 in the end. Perl 6 - second systems done right	[reply]

Only one gets set at a time. There is a form on the bottom with 2 submit buttons. Depending on which button redisplays the form, CurIDPtr is incremented or decremented. Problem is, the value of CurIDPtr is reset every time the form loads. I think I just figured that part out...	[reply]

Problem is, the value of CurIDPtr is reset every time the form loads. Of course. Each page load starts the CGI script anew, and the variable, while global, is not persistent. Perl 6 - second systems done right	[reply]
