TRACK

Enables or disables tracking of the locator position on the display device.

TRACK device-selector IS {ON | OFF}

Usage:

TRACK Plot IS ON

TRACK 702 IS OFF

Example: TRACK.BAS

Description:

ON enables tracking of the current locator on the PLOTTER IS device during DIGITIZE statements. Tracking stops when a point is digitized and the echo is left at the location of the digitized point. When the display device is a plotter, the pen position tracks the locator. When the CRT is the display device, a crosshair tracks the locator. OFF disables tracking of the current locator. To turn off the crosshair, use SET ECHO with coordinates that are off screen

The current locator is defined by a GRAPHICS INPUT IS statement and the current display device is defined by a PLOTTER IS statement. If the device-specifier is not the same as the current PLOTTER IS device, an error is generated.
