This was the norm for "Structured COBOL" ala Shelley & Cashman back when
I was taking classes in the late 70's. Most of the programming standards
I ran into required it (back when programming shops actually had standards!)

What advantage is this in either performing AAA or PERFORM
AAA-PARAGRAPH THRU AAA-EXIT?

I can't see what might be considered detrimental to it. I think it makes
the code easier for humans to read as blocks are more plainly delineated.
And the compiler probably doesn't care one way or the other. :-)

The logic doesn't make sense to me. Compilers do understand it, but
it's very much like dangerous loops where performed THRU code performs
itself.

In the same way, I like XML nested syntax requirements better than
HTML nested syntax requirements. Keep the logic clean.
