Section 10: Program Editing 141

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 calculate the net income after taxes. In the RPN program, you could add a - instruction at the end in order to calculate the net income after taxes. In the ALG program, the tax computed would need to be subtracted from the income previously stored in R9 (and this will be done by changing the sign of the tax to make it negative and then adding it to the income). You could do this as follows:

Keystrokes (RPN mode)

Keystrokes (ALG mode)
