Section 10: Program Editing 143

4.Key in the original instruction or instructions, beginning with the first instruction to be executed after the added instruction(s), and continuing through the last instruction you keyed into program memory.

Note: If program memory includes branches to program lines following that

at which the first new instruction is being added, remember to change the line number(s) specified in the i instruction(s) — as described above under Changing the Instruction in a Program Line — to the actual new line number(s).

Example: Assuming you have made the program modifications as in the preceding example, suppose you now wanted to insert a t instruction before the program calculates net income after tax so that the program will display the amount of the tax before displaying the net income after tax. The program should be modified by making the changes below:
