A listing page looks like:
-
+
LISTING_HEADER sourcefilename pagenumber
TITLE LINE
SUBTITLE LINE
If not overridden, the listing commands are:
- .title "stuff"
- Put "stuff" onto the title line
+ .title "stuff"
+ Put "stuff" onto the title line
.sbttl "stuff"
Put stuff onto the subtitle line
Set the paper size to X wide and Y high. Setting a psize Y of
zero will suppress form feeds except where demanded by .eject
- If the counter goes below zero, listing is suppressed.
+ If the counter goes below zero, listing is suppressed.
Listings are a maintained by read calling various listing_<foo>
on a line
