The easiest way to use the 'send in program' command
is touse your own class and type, that way you only
have to worry about how to structure the extra data.

Example:
- class "MIKE" -- short for your own class
- id    "PRST" -- just a 'process status' candidate 
- extra data "10001"
would translate into:
 send "10001" to program tOtherProgram with "MINEPRST"

In the other program, the card (and then up to the
stack, mainstack, etc.) will receive an AppleEvent
message:

on appleEvent pClass, pID, pSender
  switch pClass & pID
  case "MIKEPRST"
    -- this is an event of class "MIKE" and id "PRST"
    request appleEvent data
    -- this will put the actual message data in 'it'
    reply the uStatus[it] of me
    break
  default
    pass appleEvent
    break
  end switch
end appleEvent

There you have it: you just used your own AppleEvent
Class and ID to send a question to the other program,
and it replied the content of a custom property.

Hope this helped,
