One way would be to use a custom command (hander) to set the variable.  
It can 'send ... in 0'.  A possible problem is that it might queue up 
several messages before execution completes and only one is needed.

Another way is to call a routine to check what needs to be done at the 
end of routines and it can do the sends.
