hi all comp.lang.ada.reader,
could anyone tell me, why the tasking in the followed source didn't work.
the complatiton works correct, but when it was executed, the task of type
clienttasktyp didn't want to start although the 'server' task send out
an entry call ...Starten(-1).
the sourcecode is not absolutely completely.
thank you.

with Text_IO; use Text_IO;
