Subject: VAX Ada: Diffs in tasking between v 1.5 and v 2.1?
Message-ID: <1992Sep22.235629.11391@rz.uni-jena.de>
List-Id: <comp.lang.ada>

I have a prog which uses lots of tasks doing text_io.put/get on
the terminal and on files and also reading and writing system mailboxes.
The latter is implemented with QIO and AST entries.

The whole thing works fine when compiled with v 1.5, but stumbles with v 2.1.
(It seems the keyboard wait for text_io.get blocks other tasks as well.)

I'd like to know some cure for this..
