Re: How does a programmer know the arguments of a function?

Thanks guys for your replies,
In C++, we have prototype declarations in h files.
In Pascal, we don't.
Just wonder how we can make use of the standard functions
I would be glad if something like this exists in Pascal
function Rect (a : Point, b : Point....
So I know how to invoke the function with the correct number and order for

the arguments....
Thanks
Jack
