Try running this program to find the area of a circle with a radius of 5: Display: Description: This sets the program to its beginning. Stores 5 into X X The answer! We will continue using the above program for the area of a circle to illustrate programming concepts and methods. Designing a Program The following topics show what instructions you can put in a program. What you put in a program affects how it appears when you view it and how it works when you run it. Selecting a Mode Programs created and saved in RPN mode should be edited and executed in RPN mode, and programs or steps created and saved in ALG mode should be edited and executed in ALG mode. If not, the result may be incorrect. Simple Programming 13-3 Program Boundaries (LBL and RTN) If you want more than one program stored in program memory, then a program needs a label to mark its beginning (such as ) and a return to mark its end (such as ). Notice that the line numbers acquire an to match their label. Program Labels Programs and segments of programs (called routines) should start with a label. To record a label, press: letter­key The label is a single letter from A through Z. The letter keys are used as they are for variables (as discussed in chapter 3). You cannot assign the same label more than once (this causes the message ), but a label can use the same letter that a variable uses. It is possible to have one program (the top one) in memory without any label. However, adjacent programs need a label between them to keep them distinct. Programs can not have more than 999 lines. Program Returns Programs and subroutines should end with a return instruction. The keystrokes are: When a program finishes running, the last RTN instruction returns the program pointer to , the top of program memory. Using RPN, ALG and Equations in Programs You can calculate in programs the same ways you calculate on the keyboard: 13-4 Simple Programming Using RPN operations (which work with the stack, as explained in chapter 2). Using ALG operations (as explained in appendix C). Using equations (as explained in chapter 6). The previous example used a series of RPN operations to calculate the area of the circle. Instead, you could have used an equation in the program.
