Stopping or Interrupting a ProgramProgramming a Stop or Pause (STOP, PSE)

Pressing f(run/stop) during program entry inserts a STOP instruction. This will halt a running program until you resume it by pressing f from the keyboard. You can use STOP rather than RTN in order to end a program without returning the program pointer to the top of memory.

Pressing {eduring program entry inserts a PSE (pause) instruction. This will suspend a running program and display the contents of the X–register 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 1–second pause.

Interrupting a Running Program

You can interrupt a running program at any time by pressing †or f. The program completes its current instruction before stopping. Press f (run/stop) to resume the program.

If you interrupt a program and then press W, zU, or {”, you cannot resume the program with f. Reexecute the program instead ( Wlabel).

Error Stops

If an error occurs in the course of a running program, program execution halts and an error message appears in the display. (There is a list of messages and conditions in appendix E.)

To see the line in the program containing the error–causing instruction, Press zd. The program will have stopped at that point, (For instance, it might be ainstruction, which caused an illegal division by zero.)
