Re: Local variable acting static in 4GL report

Local variable acting static in 4GL report That's right - they do. I've seen (and written!) lots of reports which would break if they didn't. If you want to accumulate some form of running total (say a page total) which fails to fit the standard aggregate mechanism you really need static local variables. I must admit that until I read this post I hadn't even thought of such variables as being other than static. I suppose that's because I came to 4GL reports by way of ACE where there isn't such a concept as a local variable.
