Arbortext Editor includes fairly good introductory documentation for ACL. It's organized a little differently if you're looking at the older, "Windows Help"-style documentation or the newer, "Help Center" application. I'd start by reading through most of the "Arbortext Command Language (ACL)", "Overview of Arbortext Command Language" section, particularly the "Startup command files" topic, which describes most of the locations where you can place your code so it gets run at the right time. Under "Customizing Arbortext Editor", "Customizing startup files", the "Startup command syntax" topic will describe the various command-line options available when invoking Editor, including options to kick off arbitrary ACL code. In the Help Center, most of this information is located under "Programming", "Arbortext Command Language Reference", "Introduction to Arbortext Command Language (ACL)", but "Startup command files" and "Startup command syntax" are under "Administration", "Arbortext Editor, Styler, and Architect", "Arbortext Administrator's Guide", "Customizing Startup". Alternatively, the "Modifying the default menus" topic (again, different locations in the two help systems... try a search for this one) describes how to create custom menus to invoke your ACL code. Hope this gets you going in the right direction. -Brandon
