How to turn back?

-----------------------------------

I am doing a encyclepedia project and got a problem. I write the first page, and when I turn to second page I don't know how to turn back to the first page. Do I have to copy the whole procedure at first page or you guys have a better way to da that?

Re: How to turn back?

-----------------------------------

it depends on how you're writing the code for each page. If you're just putting everything in nested loops (not recommended if its gonna be big) then just exit until you're back in the first page.

the easiest way to do it would be to make each page a procedure. then you just need to call the procedure, instead of copy pasting tons of lines of code.

    %Your Code
end Example

procedure Example2
    %Your Code
 if return_answer = "Y" then
      cls
      Example
 end if
end Example2

%Main Program

Example2


Works like this.

I am using mousewhere button. So when I click the back button will turn back and forward button will turn forware, So how can I put the procedure within the loop?
