Below is a script I use to insert a simple block uniformly to a set of drawings. Hopefully this helps.
The easiest way for me to create a new type of script is to first do it manually on the command line and then use Hurricane's capture feature. Once I have a base script for something I usually just doctor it up as needed for other uses.
;;INSERT check print block
-INSERT
