ISCOLOR()

    ISCOLOR() returns a logical True (.T.) if a color graphics card is
    installed in the computer.

Syntax

    ISCOLOR()

Usage

    ISCOLOR() enables developers to design applications for both color and
    monochrome environments.

    The response of ISCOLOR() depends on whether the system is operating
    with a color graphics board.  Whether you are operating in color
    actually depends on whether you have a color monitor connected, and
    whether SET COLOR is ON or OFF.

    Note: some monochrome adapters with graphics capability return true
    (.T.), which can throw the poor programmer for a severe loop.
