Section 10: Program Editing 111
Adding Instructions at the End of a Program
To add one or more instructions at the end of the last program stored in program
memory:
1. Press fs to set the calculator to Program mode.
2. Press gi. followed by three digits that specify the last line you
keyed into program memory (that is, the highest numbered line, not
necessarily the line most recently keyed in).
3. Key in the new instruction or instructions.
Note: To add one or more instructions at the end of a program that is not
the last program stored in program memory, use the procedure described
below under Adding Instructions Within a Program.
Example: With the last program from the preceding section stored in the
calculator, suppose you wanted to add a - instruction at the end in order to
calculate the net income after taxes. You could do so as follows:
Adding Instructions Within a Program
If an instruction is to be added within a program, simply keying it in will replace
the instruction previously stored in that program line, as described above; the
contents of all higher-numbered program lines remain unchanged.
