Procedures - ordering.

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

I apologize if this is confusing, i realize i may not have written my code the best way. In my code I have procedures which call on other procedures and i realize that in order for me to do that I need to order them in a way so they are declared before they are called. Just to give a brief idea of what my code is like, its like this

procedure save
     ...
     main
end save

procedure addcustomer
      ...
      savebutton := GUI.CreatePictureButton (300, 100, savebutton, save)
end customer

procedure main
proc main
    Pic.Draw (background, 0, -175, picCopy)
    newcustbutton := GUI.CreatePictureButton (50, 200, newcust1, addcustomer)
    viewcustbutton := GUI.CreatePictureButton (343, 200, viewcust, viewcustomer)
    incexpbutton := GUI.CreatePictureButton (639, 200, incexp, incomeexpense)
end main
main



As you can see, the 'main' procedure needs the addcustomer procedure to be above it, the add customer needs the 'save' prcedure to be above it and the save needs the main to be above it. Right now the turing tells me that 'main' has not been declared under the save procedure. Is there any way of calling a procedure when it has not been declared above its calling? I am using GUI so i need to use procedures.

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

procedure main
proc main 

Why are you declaring this twice? (unless there is a difference and there is a legit reason)

No that was just a typo.
