I have B.A. in English from American University, plus 15+ years exper. writing end user instructions for point of sale applications. I can write documentation in simple, easy-to-undertand steps, including field-specific context details, such as field length, upper/lower case, numeric-only, and so forth. At my last job, I created numerous electronic forms, and wrote field-specific (press F1 for help) Help text describing field parameters and data contents (what is a VIN number, etc.).
