Placement of Function code

When writing a script, is there a certain place to put your own functions? Do they have to be in the front of the script, say, after the global variable casting?

If you put the functions at the end, it would seem like they are out of the way of the main program, or does that not work?

I would experiment with that, but I'm remote at the moment and do not have anything to compile with, so cannot try.

Is there anything that can confirm a compile while you are away from your main system?

Yes, functions and global variables need to be declared (written) before you use them.

This is because the compiler makes a single pass through your code.

The following works:

integer MyGlobalVariable;

DoSomething()
{
   llWhisper( 0, (string)MyGlobalVariable );
}

default
{
state_entry()
{
DoSomething();
}
}

There's nothign that comes with SL that allows you to compile your code outside of SL, but there's no reason why someone couldnt build one.

keep in mind too that a function cannot call another function that's below it.

// funcs
do_this()
{
  llSay(0, "hi");
}

do_that()
{
  do_this();
  end_me();
}

end_me()
{
  llDie();
}

default
{
  state_entry()
  {
    ....
  }
}

...this won't compile because do_that() can't call the function below it (end_me()), it could however call the do_this() function. The script will fail to compile if you call functions out of order. Due to how the compiler compiles (as stated above) -- it compiles in order, and the call to the end_me() function is invalid, because, to the compiler, "end_me()" has not yet been declared.

Ok thanks, I thought that was the case about the declaration.

Also, I think I will try to stay away from having one function call another, but that is good to remember also. =)
