Has no effect and is included in LiveCode for compatibility with imported SuperCard projects.Syntax:
set the penBack [of <object>] to <colorNumber>
In SuperCard, the penBack property specifies the color used to draw borders. In LiveCode, the border color is determined by the borderColor property.
The penBack property is always set to empty. A handler can set it to any value without causing a script error, but the actual value is not changed.
