Looking at the CALL verb, I see ILE COBOL allows USING BY xxxx Identifier where 
xxxx can be REFERENCE, CONTENT or VALUE. I normally wouldn't have a big issue 
with that, but each of those allows the addition of ADDRESS OF between xxxx and 
Identifier.

If I code:

         CALL MyProg USING BY VALUE ADDRESS OF My-Variable

how is that different from:

         CALL MyProg USING BY VALUE My-Variable

or:

         CALL MyProg USING BY REFERENCE ADDRESS OF My-Variable

or any other variation???

I don't see clear discussion in the manuals on this point. I thought I knew the 
difference between REFERENCE, CONTENT and VALUE; but is ADDRESS OF particularly 
meaningful for all of REFERENCE, CONTENT and VALUE? Is it different for each?

Thanks for any insight.
