Hmm, interesting. I did not find any mention of "NEXT SENTENCE" in any
of the documentation I initially used as references for the COBOL language,
but based on the discussions I've found on the web, it looks like NEXT
SENTENCE is an unconditional jump to the statement immediately following the
period of the sentence containing the NEXT SENTENCE statement, as you've
said.

I think this would be one one case where I would have to add a new
paragraph name (to act as a label), then change the NEXT SENTENCE to a GO TO
which jumps to that label. All the while, I have to be check for any PERFORM
or PERFORM THRU statements that I might have to update to reflect the
addition of this new paragraph.

Thanks for the tip, I might have to factor in this new issue into the
algorithm design.
