BLANKER is a Commodity Exchange program that causes the screen to go blank if no mouse or keyboard input has been received in the specified number of seconds. The SECONDS argument enables you to specify the number of seconds that must pass. The acceptable range is from 1 to 9999 seconds. The default is 60 seconds.

CX_PRIORITY sets the priority of BLANKER in relation to all other Commodity Exchange programs. All the Commodity Exchange programs are set to a default priority of 0.

CX_POPKEY enables you to specify the hot key for the program. If more than one key is specified, be sure to enclose the entire argument in double-quotes (i.e. CX_POPKEY="Shift F1").

CX_POPUP no will prevent the BLANKER window from opening. (By default the program window opens when the command is invoked.)

The SHOWHINTS YES option can be used to display usage information if you position the cursor over selectable items.

LEFT, TOP, WIDTH and HEIGHT can be used to customise where the BLANKER window should appear on the screen and the size of the window.

DPMSLEVEL enables to specify values for the Display Power Management System. The first value DPMSSTANDBY <stand-by> is the standby time (in seconds - default=600), the second value DPMSSUSPEND <suspend> is the suspend time (in seconds - default=600), while the third value DPMSOFF <active-off> is the active-off time (in seconds - default=1800).

If CYCLECOLORS yes is specified, BLANKER will cycle through a series of colors. If CYCLECOLORS no is specified, BLANKER will display the default color. The default is 'yes'.

If ANIMATION yes is specified, the screen will display a series of random splines. If ANIMATION no is specified, a blank screen will appear. The default is 'yes'.

Only valid if CYCLECOLORS yes or ANIMATION yes has been specified, SPEED <speed> can be used to control the speed of the color cycling or animation. If specified, <speed> can range from 0 to 100%, the higher the value the faster the onscreen activity. The default is '100%'.

To exit BLANKER when it has been started throught the Shell, press Ctrl+C or use the BREAK command.

Example 1:

3.OS4:> BLANKER SECONDS=45
the blanker window will open, and 45 will be displayed inside its text gadget. If no mouse or keyboard input is received during a 45 second interval, the screen will go blank.

Example 2:

3.OS4:> BLANKER CX_POPUP=no
the Blanker program will start. If no input is received within 60 seconds (the default), the screen will go blank. The Blanker window will not open.
