It contains the value of line 1. That is, line one without any line
delimiters.
I like to think of it as a constant rather than a variable, a constant
that is new each time through.
The Revolution style is to put item and line delimiters between datums,
but it will also accommodate putting them after datums. This is
important in representing empty datums. If datums are never empty,
then putting delimiters between is fine. I mention this, in case you
are surprised about how many lines are processed in such a loop.
