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.
