Thanks all for answers!

I think that like say Mr. Nygaard: "Programming is understanding", independent of the used languages. But even language have yours tricks and my intention here is know more about then in pic basic pro.

I describe the current work for give some ideas and find similars works made with the same language, in last metrics of the entire project, I discover that all project have 11675 lines (excluding commentaries and pre-processor directives). So to implement new methods, I will need know more about the greats techniques using pic basic pro and re-write some pieces of code. In firs view of actual code, I´ve found some unstructural programming method (large usage of goto´s) and wast time in main loop using pause , serin2 and another polling methods. My first intention is re-write these methods in structural way, withou of use of goto´s statements and communications serial polling for two hardware serials.

In essence, the product is one avl then I need some peaces of code giving support for "application" code.

Again, thanks a lot ...
