Application Parameters Record

You specify an application parameters record in the launchAppParameters field of the launch parameter block whose address is passed to the LaunchApplication function. This record specifies the first high-level event to be sent to the newly launched application. The application parameters record is defined by the AppParameters
data type.

TYPE AppParameters = 
   RECORD
      theMsgEvent:      EventRecord;       {event (high-level)}
      eventRefCon:      LongInt;           {reference constant}
      messageLength:    LongInt;           {length of buffer}
      messageBuffer:    ARRAY [0..0] OF SignedByte;
   END;
