Help needed with tasking

[Richard Francis <com40008@diana1.cs.paisley.ac.uk>]

I am writing a traffic lights sim using tasking. Can someone help me
with how tasks work? You can't call an entry from within another, is
that right? eg
task body a is
select
accept x do
--something
a.y;
end x;
or
accept y do
--something
end y;
end select;
end a;

what else can or can't you do?
