I think the issue Bill was trying to point out was that the code was
inlined, or COPYed in two (or more) locations. If it were merely an issue of
having correct code, and not wanting to touch that code for fear of breaking
it, the code could have been put in a paragraph, and COPYed onced, and to
simply PERFORM that paragraph.
