Hear what the RM (11.4) says (note especially 11.4 (4): 3 When an exception occurrence is raised by the execution of a given construct, the rest of the execution of that construct is abandoned; that is, any portions of the execution that have not yet taken place are not performed. The construct is first completed, and then left, as explained in 7.6.1. Then: 4 � If the construct is a task_body, the exception does not propagate further; 5 � If the construct is the sequence_of_statements of a handled_sequence_of_statements that has a handler with a choice covering the exception, the occurrence is handled by that handler; 6 � Otherwise, the occurrence is propagated to the innermost dynamically enclosing execution, which means that the occurrence is raised again in that context. >But as far as seeing text displayed in the console window indicating that an >excpetion was raised should always >occur, at least in every other Ada compiler i have used.

Make systematic use of handlers for Tasking_Error. Be prepared to handle exceptions during a rendezvous . Consider using a when others exception handler. Consider using an exception handler for a rendezvous within the main loop inside each task. Place an exception handler for others at the end of a task body. Consider having each exception handler at the end of a task body report the task's demise. >So with that does anyone know why i am not getting text messages telling me >an exception was raised? > Yes .. because If the construct is a task_body, the exception does not propagate further.
