84 Section 8: Program Editing
Making a deletion or additon of a program line alters the line
numbers of those program lines following. By editing the program
from the end backwards, you can preserve the original line
numbers of parts of the program not yet edited. This allows you to
access remaining lines by their original numbers. The editing steps
below assume the concatenation program occupies line 001 to 010.
