PVIEW

Command

 

 

 

Type:

 

 

 

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.

Access:

!°LPICT LPVIEW

( °is the left-shift of the Nkey).

Example:

The program

 

 

 

 

 

 

 

« { # 0d # 0d } PVIEW 7 FREEZE »

 

 

displays PICT in the graphics display with coordinates { # 0d # 0d } in the upper left

 

corner of the display, then freezes the full display until a key is pressed.
