Displaying Information without Stopping

Normally, a program stops when it displays a variable with VIEW or displays an

equation message. You normally have to press

to resume execution.

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 1–second pause. In this case, no scrolling or keyboard input is

allowed.

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.

This will halt a running program until you resume it by pressing

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

during 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.
