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
g 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.
