SCREENATTR()

Syntax:     SCREENATTR([<expN1>][,<expN2>])

Arguments:  <expN1> is the line from which to extract the attribute
            (default: cursor line).
            <expN2> is the column from which to extract the attribute
            (default: cursor column).

Returns:    A numeric value.
            The value corresponds to the attribute at the position
            indicated.

Usage:      SCREENATTR() supplies the actual screen attribute from line
            <expN1> and column <expN2>.  It is then possible to
            determine targeted attributes and store them for subsequent
            use.

Notes:      The current cursor position is used if the line and/or the
            column is not supplied.

Library:    CT1.LIB

            * The attribute on the actual column position
            * in line 23.

            var = SCREENATTR(23)

            * The attribute on the position column 70,
            * line 23.
