Calling a Function from RPG Program having multiple functions ?

["Luqman" <luqman@xxxxxxxxxxxxxxxx>]

I have created an RPG ILE Program which contains multiple functions, just
like a function library.

Now  how can I call any function from another RPG Program.

Say: I have two functions in RPG Function Program, function 1 and function 2

Function 1 returns string value
function 2 returns numeric value

Now I want to call Function 2 from another RPG Program with :

Call 'myLibrary'
Parm ????

But I don't know how to mention, what function I am calling ?

Any idea please ?

Best Regards,
