Defining Strings for Serial Ports and Viewports

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.
