Re: Still not clear about global functions

Hi, Alan.

re:

You could, but it's not good to publish source code.

One of the great advantages of assemblies ( DLLs ) is that they
give you a measure of protection against those who would simply
copy your source code.

re:

Sure it is...

Using classes is more efficient and helps you organize your code functions.

Tell "everyone" that OOP *is* the standard,
and the most efficient, way to manage functionality.
