Two questions to better understand values

If I used dot notation like that, would it be okay?

So being able to use values like .width, .height etc, would cut down on the number of variables I create and it would make everything more readable when looking back after a year.

Bear in mind that the dot extension is for accessing numbers that are already in the Variable. If your Variable VarShape contains 21,33,44,88 for example you can use the dot notation to retrieve one of those numbers, or to perform a calculation using those numbers (like to work out the mid point where the window is positioned on screen). In other words you would not create a variable VarShape.width = 10. But you would use the syntax VarShape.width to retrieve one of the four numbers already in VarShape. And you could only use that dot notation in a Calculate field (not in a text field).

By coincidence there is another Thread on this exact thing which explains it much better than I can. The answer from @peternlewis in this post is very good I think:

How to Create a Rectangle Variable

Yes. There isn't any magic about either of them. v.x is just short for v[1], and v.MidX is basically just short for v[1]+v[3]/2 (and errors if the variable does not have two, four or five array members (4 or 5 for MidX)).
