Example 3 – Using the Draw Line Code
A draw line code was used to draw the horizontal line separating the display
title (“Acme . . .”) from the rest of the viewport.
Example 3
Shown below is the string text used to create the horizontal line. Recall that
the draw line code follows the format Dx,y dx,dy.
x y dx dy
In this case, the x value (the x–coordinate of the starting point of the line) is
0, indicating the left edge of the viewport. The y value is not a specific
value; rather, it is the
* symbol (which means “cursor position”); this
conveniently allows you, in this case, to vertically position the line’s starting
point using the string
Pick & Place function (on the Define String menu).
The dx value (the horizontal component of the length of the line drawn) is
479, which is the width of the viewport.
Note: You can find out the dimensions of a viewport by enabling the help
message while using
Pick & Place to position the viewport). The dy value
(the vertical component of the length of the line drawn) is 0, which indicates
a horizontal line.
