Stopping or Interrupting a Program
Programming a Stop or Pause (STOP, PSE)
• Pressing FrTsI (run/stop) during program entry inserts a STOP in
struction. This will halt a running program until you resume it by
pressing IrTsI 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 Bl lbl/rtn I {PSE} during program entry inserts a PSE
(pause) instruction. This will suspend a running program for about
1 second and display the contents of the X-register.
Interrupting a Running Program
You can interrupt a running program at any time by pressing [c] or
FrTsI. The program completes its current instruction before stopping.
Press [rTsI (run/stop) to resume the program.
If you interrupt a program and then press IXEQ I, IGTO I, or {RTN},
you cannot resume the program with IR/SI. Re-execute the program
instead (fxEQl label).
Error Stops
If an error occurs in the course of a running program, program execu
tion halts and an error message appears in the display. (There is a list
of messages and conditions in front of the indexes.)
To see the line in the program containing the error-causing instruc
tion, press Hi prgmI. The program will have stopped at that point.
(For instance, it might be a -r instruction, which caused an illegal
division by zero.)
