The
ERASE procedure erases the screen of the currently selected
graphics device (or starts a
new page if the device is a printer). The device is reset to alphanumeric mode if it has such a mode (e.g., Tektronix terminals).
Calling Sequence
ERASE
[, Background_Color]
Arguments
Background_Color
The
color index for the screen to be erased to. If this argument is omitted ERASE resets the screen to the default background color (normally 0), stored in the system variable !P.BACKGROUND. Providing a value for
Background_Color
overrides the default.
Warning: Not all devices support this feature.
Keywords
CHANNEL
The channel or channel mask for the erase operation. This parameter has meaning only when used with devices that support true-color or multiple-display channels. The default value is !P.CHANNEL.
COLOR
Specifies the background color. Using this keyword is analogous to using the
Background_Color
argument.
Example
TV, DIST(255) ;
