Passing Variable Values back and forth between EAs and Included & Library files ?

I'd appreciate someone pointing me in the right direction on this,

Thanks (< 8)

pass variables to/from functions via their argument list and return value. Avoid the use of global variables, global variables are bad programming style. Pass everything via function arguments. It makes no difference where the function is defined.

use pointer variables as function's parameteras .

I'm not quiet sure just what exactly these are, but it gives me some topics to track down and decipher.

Thanks folks (< 8)
