Is it really necessary to write to the code segment? Why not keep the
values to be scanned in the data segment, solving both the problems
you've mentioned?

[Indeed, you would normally put the data in the data segment. But this
does write to the end of an otherwise read-only table. On the '86 the
scan has a length count which avoids the need to stash the value at the
end of the table; this hack was really for the PDP-11. -John]
