PVIEW
Type: Command
Description: PICT View Command: Displays PICT with the specified coordinate at the upper left corner of
the graphics display.
PICT must fill the entire display on execution of PVIEW. Thus, if a position other than the upper
left corner of PICT is specified, PICT must be large enough to fill a rectangle that extends 131
pixels to the right and 80 pixels down on the HP 50g and 49g+ (64 pixels down on the HP 48gII).
If PVIEW is executed from a program with a coordinate argument (versus an empty list), the
graphics display persists only until the keyboard is ready for input (for example, until the end of
program execution). However, the FREEZE command freezes the display until a key is pressed.
If PVIEW is executed with an empty list argument, PICT is centered in the graphics display with
scrolling mode activated. In this case, the graphics display persists until is pressed.
PVIEW does not activate the graphics cursor or the Picture menu. To activate the graphics cursor
and Picture menu, execute PICTURE.
