When it's time to pop the question (in a JavaScript response dialog), Kas shows you how.

In his article "Automating Workflows," David Zwang explores the what, how and why of process automation, including a look at some basic automation tools and offering insights on ways to facilitate new workflows.
Bernd Zipper of Germany chats with Stephan Jaeggi of Switzerland about his long experience working with PDF in Prepress, and in particular about the "opportunities and dangers" Jaeggi sees for those who attempt to build a home-grown PDF workflow. His advice: "You don't have to switch to a PDF workflow all at once ... take it step by step. Run the PDF workflow in parallel with your existing PostScript workflow."

PDF is one of the most brittle and unforgiving formats I've ever worked with, in the sense that if you introduce even one stray byte into the middle of a file, you stand a 99% chance of wrecking the reading frame for the whole file (kind of like a frameshift error in DNA giving rise to "nonsense proteins"), totally breaking the world.

A custom keystroke filter to emulate one of those Department-of-Motor-Vehicle sort of forms where you have a little square box for every letter of your name, and you can fit only one character to a box.

Kas reveals a method of determining object types programmatically. How DO you tell whether the function was passed an Array versus a String?
Ted Padova
Ted Padova, author of the Acrobat PDF Bible, provides a detailed (17 parts) step-by-step guide on creating and using Acrobat PDF Forms. Many of the resources and examples cited in his article are also available for download.

Kas has been trying to find a way to store functions as persistent globals, so that he can come back to them, from ANY future PDF form that a reader downloads.

Kas illustrates the "arity" function that is used for counting arguments in JavaScript.
Kas Thomas
Data types are implicit and (to a degree) contextual in JavaScript, which makes life easy on the programmer, for the most part. But there are times when it is helpful or even essential to know whether two variables are of the same type.
Kas Thomas
It's usually a good idea to initialize variables with sane values as soon as they are created (and sanity-check incoming argument values before using them). Intialize your form fields to rational values. Don't just leave them blank or zero. If you do, you don't know what kind of nonsense might happen.
