2. Move to the program line number immediately preceding the
position where you want to insert the new instruction.
3. Keyin the new instruction. It will be loaded into the next line
of program memory. All subsequent instructions will be
“bumped” down (renumbered) one line in program memory.
Because each new instruction you insert causes all subsequent
instructions to be renumbered, inserting changes in a program is
simplified by beginning with the change farthest from line 000,
then working back toward the beginning of the program.
Example. Toinsert a instruction after the [+]instruction:
