I'm sure there's an official name, but I don't know what it is. If you
used RDi, you could press Ctrl-Shift-O and see them for yourself :-)

Indeed. Thanks for humoring me and being patient.

They are vertical lines and horizontal arrows which connect the tops and
bottoms of control blocks, for example IF and ENDIF. If there's
nesting, there is one line for each control block.

Aha. I managed to find this:

https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_61/rzasc/sc09250739.htm


It mentions Ctrl+Shift+O as a way to "show block nesting".

You say there's one line for each block, which I take to mean there
are simultaneous, parallel vertical lines when blocks are nested. If
I'm reading that correctly, the horizontal arrows are like the Bn, Xn,
and En in compile listings, and there are n vertical lines connecting
them.

Which seems nice. But that area in the margin looks pretty small; what
happens when you are in that 100-line, 12-deep control block?

They are created on the fly, and as far as I can tell, not stored with
the source member in the cache. They are not persistent; RDi won't show
them tomorrow.

OK, that all makes sense. It should be able to recalculate them as
needed based on lexical analysis of the source code. It was only when
I was thinking you might mean horizontal rule (like a comment which
consists of hyphens or equal signs or asterisks) that persistence even
crossed my mind.
