There's an important difference between a network application and a
subfile -- and that's that the network program is talking to a different
computer program that's outside of your control.  It has to do what that
other program is expecting, or it will fail.   Since that program was
written by another programmer, who has the flexibility to design the
code any way he/she wants to, there's a lot of variations on what must
be done.

A subfile, by contrast, doesn't need to communicate with another
programmer's work.  Therefore, the decisions about how to make your
program flow are entirely up to you.  You can simply lay down guidelines
that say "clear, loop (read recs, increment RRN, write rec), display
footer, display sflctl".   That way will always work, because there's no
variable process that it has to conform to.

The HTTPAPI process is dependent on the web server.  The subfile isn't.
