The RCL instruction is not necessary, but it is convenient because it brings the VIEWed variable to the Xregister, making it available for manual while viewing a VIEW display would have the calculations. (Pressing same effect. ) The other application programs in chapters 15 through 17 also ensure that the VIEWed variable is in the Xregister as well -- except for the "Polynomial Root Finder" program. Using Equations to Display Messages Equations aren't checked for valid syntax until they're evaluated. This means you can enter almost any sequence of characters into a program as an equation -- you enter it just as you enter any equation. If flag 10 is set, equations are displayed instead of being evaluated. (Flags are discussed in detail in chapter 13. ) When the message is displayed, the program stops -- press to resume execution. If the displayed message is longer than 14 characters, the annunciator turns on when the message is displayed. If you don't want the program to stop, see "Displaying Information without Stopping" below. Example: INPUT, VIEW, and Messages in a Program. Write an equation to find the surface area and volume of a cylinder given its radius and height. Label the program C (for cylinder), and use the variables S (surface area), V (volume), R (radius), and H (height). Use these formulas: 1214 Simple Programming V = R2H S = 2 R2 + 2 RH = 2 R ( R + H ) Keys: (In RPN mode) Display: Description: Program, entry; sets pointer to top of memory. C R H Labels program. Calculates the surface area. Simple Programming 1215 Keys: (In RPN mode) V S { } Display: Description: Displays volume. Cancels program entry. Now find the volume and surface areaof a cylinder with a radius of 2 1/2 cm and a height of 8 cm. Keys: (In RPN mode) C value Display: Description: Starts executing C; prompts for R. (It displays whatever value happens to be in R. ) Enters 2 1/2 as a fraction. Surface area in cm2. 2 8 1 2 value Displaying Information without Stopping Normally, a program stops when it displays a variable with VIEW or displays an to resume execution. You normally have to press If you want, you can make the program continue while the information is displayed. If the next program line -- after a VIEW instruction or a viewed equation -- contains a PSE (pause) instruction, the information is displayed and execution continues after a 1second pause. In this case, no scrolling or keyboard input is allowed. 1216 Simple Programming The display is cleared by other display operations, and by the RND operation if flag 7 is set (rounding to a fraction). Press to enter PSE in a program. The VIEW and PSE lines -- or the equation and PSE lines -- are treated as one operation when you execute a program one line at a time. Stopping or Interrupting a Program Programming a Stop or Pause (STOP, PSE) Pressing (run/stop) during program entry inserts a STOP instruction. from the This will halt a running program until you resume it by pressing keyboard. You can use STOP rather than RTN in order to end a program without returning the program pointer to the top of memory. This will suspend a running program and display the contents of the Xregister for about 1 second -- with the following exception. If PSE immediately follows a VIEW instruction or an equation that's displayed (flag 10 set), the variable or equation is displayed instead -- and the display remains after the 1second pause. Interrupting a Running Program You can interrupt a running program at any time by pressing program completes its current instruction before stopping.
