CAD Lisp Code Help

[dber]

Hi, 

I have a LISP code to help clean up some incoming files from Civils as we work on projects. 

I wanted to add to this code that I got, and was wondering if there are any lines of code that could make AutoCAD:

1. Change Allow Exploding to "Yes" for all blocks

2. Select all hatches in drawing and change Annotative to "No"

 

I heard the commands can be limited, so just wondering if its possible and what it might look like.

 

Thanks!
