This script does a search and replace to change use of dotted parameters x. and y. etc. to x and y in scripts and labs.
It does not check if one of the undotted names has already been used in a definition. In practice, I found very few such in my own code, and it was easiest to fix them up manually. A smarter program would detect such uses.
