After Resrc Select before Get Appts embed is provided for the developers who are combining several appt files into one IMDD file for reading.  This gives you a chance to reload the file with the appointments before reading them, and only hits the files once instead of using another embed for this.

After Clear Colors Routine embed is provided for each instance of the template for the developer to make any changes they want.

Before Adding to List Queue embed is added for each instance of the template installed for final tweaking of all items before it is added to the display queue.

Setup Before Get Appointments  embed is added for each instance of the template for developer to change the settings of the display of the data from their own Config files, etc.

TakeRecord Appt embed is provided for each instance of the template to provide a point to construct local variables if you need to use them for the display line or extra Tooltips display lines.  You can also do your own filtering here by examining the data and adding the Cycle statement.

The rest of the embeds are wrapping the standard file handling (Insert, Change, delete, view) and when you drop an appointment after dragging.
