@...TO


Syntax:     @ <expN1>, <expN2> TO <expN3>, <expN4> [DOUBLE]

Purpose:    To draw single or double line boxes on the screen.

Arguments:  <expN1...expN4> define the coordinates of the box.
            ExpN1 and expN2 define the upper left corner and expN3 and
            expN4 define the lower right corner.  If the two row
            coordinates (<expN1> and <expN3>) are the same, Clipper
            draws a horizontal line.  If the two column coordinates
            (<expN2> and <expN4>) are the same value, Clipper draws a
            vertical line.

Option:     Double: The DOUBLE clause paints the box with a double
            line.  If this clause is not specified, the box is painted
            with a single line.

Usage:      @...TO is very similar to @...BOX with two exceptions.
            First, @...BOX allows you to define the characters of the
            box and second, it supports a fill character.

Library:    CLIPPER.LIB
