File: box_funcs.4gl

Description:
	Set of functions, on three levels from the simple to the sublime, to 
	manage pop up message windows, small limited menu boxes, and 
	standardized dialogue boxes.  Quick functions allow one to open and 
	manage warning, message, and Yes/No menu boxes with a single call.
	"Pos" functions add the ability to specify that the box should open 
	at the top of bottom of the current window.  "Pos-to" functions allow 
	one to specify the line and column position for the box to open within 
	the current window.  Finally low level functions permit multiple line 
	message boxes and full control of the box's behavior.  Boxes auto size 
	to accomodate the message text.
