Editing a Program
You can modify a program in program memory by inserting and de
leting program lines. Even if a program line requires only a minor
change, you must delete the old line and insert a new one.
To delete a program line:
1. Select the relevant program or routine (H|gto| label), activate
program entry (BHprgmI), and press [r) or HH to locate the
program line that must be changed. Hold the arrow key down to
continue scrolling. (If you know the line number you want,
pressing Hi gto IQ] label nn moves the program pointer there.)
2. Delete the line you want to change by pressing g). The pointer
then moves to the preceding line. (If you are deleting more than
one consecutive program line, start with the last line in the
3. Key in the new instruction, if any. This replaces the one you
4. Exit program entry ([c] or Hi prgm I).
To insert a program line: Locate and display the program line that
is before the spot where you would like to insert a line. Key in the new
instruction; it is inserted after the currently displayed line.
For example, if you wanted to insert a new line between lines A04
and A05 of a program, you would first display line A04, then key in
the instruction or instructions. Subsequent program lines, starting
with the original line A05, are moved down and renumbered
