Compatibility: Version 6.7.x and 6.8.x

You will see the word AREA used in just about every single plug-in command. AREA is the variable name to identify the plug-in area you are using.

For example, let's say that you have placed 4D WRITE on a form. In the properties dialog box, under objects, you will see a field for"Variable Name." Every time you want to manipulate the area, you need to tell 4D what to do and to whom.

Let's look at a simple command.
WR DELETE SELECTION (AREA)

WR DELETE SELECTION(MyWrite)
`do what? Delete the selection
`to whom? MyWrite

In the above example, MyWrite is the "Variable Name."
