I don't know where you got that idea. No, I didn't say that. My point
to Dark was that you can't call a function that hasn't been defined in
your script somewhere.
If you recall Dark said he didn't understand why he was writing an
add_numbers(() function when in the body of main he had already added
the numbers 3 and 5. What he failed to grasp at that point is that the
add_numbers function he used in main() hadn't been created yet. He
actually defines the contents of the add_numbers() function later on
in his script. Otherwise you can't call a function that doesn't exist.
A better way to explain it is when you open a book to the table of
contents and it tells you chapter 5 is on page 75. Well, what happens
if there is no page 75 in the book? The obvious answer is you can't
look up the contents of chapter 5 right?
Well, when writing scripts a similar concept comes into play. If you
write a little piece of code like
void main ()
int result = add_numbers (3, 5);
What you are telling main to do is to call the add_numbers function,
which should exist somewherein your script, and take the numbers 3 and
5 and add them together, and then return the result which happens to
be 8. If the add_numbers() function doesn't exist it is like turning
to a blank page in the book and the script can't continue. That's all
I was getting at.
However, to answer your immediate question i believe main can appear
anywhere in a BGT script. Although, in a lot of the examples I've
seen it appears at the top of the scripts. This makes sense since it
is the entry point for the script and initializes everything else.
