send to program debuging

[Mike McManus]

How would you debug "send to program" commands used to send commands to 
other stacks when you are developing? To be more clear. My main stack 
sends commands to other freestanding stacks, which will be independent 
applications when built. Buut during the development process I don't 
want to compile things everytime I want to test it. Using IAC to create 
a server application that controls other stacks. They will talk between 
each other.  Sending and replying after the complication of certain 
activities. The send command isn't exactly the same...and of course 
then I would have to go back and change the commands before I built the 
standalones.

Ideas?
