QUESTION
 How can I signal to VisualAge the end of a Rexx program started with program
 starter?

ANSWER
 If you are interested in being notified when a program started from
 the program starter ends, the best way to proceed is to subclass
 the AbtProgramStarter within VisualAge. This part uses the DosStartSession
 API to start your programs. DosStartSession can be invoked so that
 the OS/2 session manager will write a data element into a queue
 that you specify when any child session ends. Your subclass needs
 to create the queue and issue the DosReadQueue to be notified when
 the child session ends. See the OS/2 CP Reference for more information
 on this API. AbtProgramStarter>>startProgram executes the
 DosStartSession.

 I believe that you can also retrieve the return code of your program
 with this technique.
