NUMLOCK([lExpression])

Parameters

lExpression

Turns the NUM LOCK key on or off. If lExpression is true (.T.), the NUM LOCK key is turned on; if lExpression is false (.F.), the NUM LOCK key is turned off. NUMLOCK( ) returns a logical value corresponding to the NUM LOCK key setting before NUMLOCK(.T.) or NUMLOCK(.F.) is issued.
