NUMHIGH()

Syntax:     NUMHIGH(<expH>)

Arguments:  <expH> is either a decimal number or a hexadecimal string
            of digits.

Returns:    A numeric value.
            The high value byte of the 16-bit number <expH> will
            be returned.

Usage:      NUMHIGH() will break down a 16-bit number into its two
            bytes and return the high byte as the result.  This is
            particularly important when using functions such as
            SCANKEY(), GETCURSOR(), etc.  It is then possible to
            separate the two bytes of the keyboard scan codes.

Notes:      An invalid argument will lead to the result -1.

Library:    CT1.LIB

Examples:   * Breaking down the combined return value of
            * GETCURSOR().

            ? "Starting line of the cursor is:" + NUMHIGH(GETCURSOR())
