@...TO

    To draw single or double line boxes on the screen.

Syntax

    @ <exp N1>, <exp N2> TO <exp N3>, <exp N4> [DOUBLE]

Arguments

    <exp N1..exp N4> 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, Clipper draws a vertical line.

Options

    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.  @...TO, however, is easier to use since you do not
    have to remember the box characters.
