I use Epsilon programmer's editor (little E for PC, evolved from Emacs) which I learned at Carnegie Mellon almost 20 years ago.  Notepad/Wordpad and application development environments with built-in editors have made it hard to explain to DBAs and to developers what a real programmer's editor is.  Epsilon is more useful and flexible than specialized "data cleansing" tools as well.  In my view, a person who doesn't have a tool that performs a regular expression search is not a **real** programmer.

Query Analyzer does its job; Epsilon does its job; they work well together.  Code repository is a separate job, not to be confounded with editing.
