Section 8 Programming Basics Why Use Programs? A program is simply a sequence of keystrokes that is stored in the calculator. Whenever you have to calculate with the same sequence of keystrokes several times, you can save a great deal of time by incorporating these keystrokes in a program. Instead of pressing all the keys each time, you press just one key to start the program: the calculator does the rest automatically! Creating a Program Creating a program consists simply of writing the program, then storing it: 1. Write down the sequence of keystrokes that you would use to calculate the quantity or quantities desired. 2. Select the mode you want to use (by pressing f] or f[). Note: Programs or steps created and saved in RPN mode should only be executed in RPN mode, and programs or steps created and saved in ALG mode should only be executed in ALG mode. (You can also create steps in your program to switch to the appropriate mode.) 3. Press fs to set the calculator to Program mode. When the calculator is in Program mode, functions are not executed when they are keyed in, but instead are stored inside the calculator. The PRGM status indicator in the display is lit when the calculator is in Program mode. 4. Press fCLEARÎ to erase any previous programs that may be stored inside the calculator. If you want to create a new program without erasing a program already stored, skip this step and proceed as described in Section 11, Multiple Programs. 5. Key in the sequence of keystrokes that you wrote down in step 1. Skip the beginning keystrokes that enter data, which would differ each time the program is used. 104 File name: hp 12c pt_user's guide_English_HDPMF123E27 Page: 104 of 275 Printed Date: 2005/8/1 Dimension: 14.8 cm x 21 cm
