Check current version of AppleScript

check_applescript_version.applescript

(* While trying to figure out what version of AppleScript I had installed,
  I came across this article: https://www.safaribooksonline.com/library/view/applescript-in-a/1565928415/ch01s05.html
  The problem? That article is from 2001 and no longer works!
  The script provided in that article will *always* return 1.0 as your version, 
  because it just checks the version of the currently executing script (implicitly set to 1.0)
  
  Instead, just use this script to output the version in a dialog.
