The simplest software applications are key-in scripts. A key-in script is a sequence of key-ins that are stored in a text file. For example, the following script sets the active level, active color, and active line weight:

active level Level 3
active color blue
active weight 2

The Batch Process utility provides a convenient way to create a script and apply it to a set of files or directories. You can also use the Key-in window to run a key-in script.
