Hi guy,
i am try to create a custom browser screen to show some information and also allow customer to edit same values for register. due to the limitation of it, I think i need too use karel to go through more complicated operation. however, i am stuck with how to pass data between the custom screen and karel program. for example , i insert the PR num to show. Pr detail will shown and customer can view each element, and there will be an edit box for them to edit thee value of each element.
can someone guide me on this. thanks
