Illustrator Insert Page Numbers v 2 Script

#target illustrator
//#targetengine main

// script.name = insertPageNumbers_v2.jsx; // works with CS4 & CS5
// script description = Inserts page numbers (or any other text) to all artboards in the active document;
// script.required = at least one open document
// script.parent = CarlosCanto // 5/25/12;
// script.elegant = false;

// script.updates = added options to insert Date, Time, Full File Name, & File Name;
//                  added a button to clear previous entered data;
//                   dialog stays open, to be able to input data in multiple locations
//                   only one layer is created on multiple runs

// Notes: The script creates a new layer (Page Numbers) then adds a text frame per Artboard that act as footer or header text.
//      Its primary function is to insert Page Numbers, but it could be used to insert any other kind of information.
