Par2: Using MessageHook
2012-03-15 -- Graham Dawson
 
Best bet would be to use prop:messagehook and 'hook' the message procedure.

All your existing message lines stay the same, you just add a single procedure and two
code lines,
one to hook and one to release the hook.

There's not much in the Help about this but you just define a window procedure using the
prototype in BUILTINS.CLW and then set the hook to the 
address of _your_ message window

system{prop:messagehook} = address(MyMessage)

To reset use

system{prop:messagehook} = 0 !*** zero ***

MyMessage prototype
(STRING,,,,UNSIGNED=0,UNSIGNED=0),UNSIGNED

MyMessage parameters
(input_text,caption,icon,buttons,default,style)

Now you can add a timer to the window and auto-close with post event:closewindow if no
user response.
