Intermediate Program Stops

Use ´ © (pause) as a program instruction to momentarily stop a program and display an intermediate result. (Use more than one ©for a longer pause.)

Use a ¦ (run/stop) instruction to stop the program indefinitely. The program will remain positioned at that line. You can resume program execution (from that line) by pressing ¦during Run mode, that is, from the keyboard.

Running a Program

Run Mode. Switch back to Run mode when you are done programming: ¥. Program execution must take place in Run mode.
