If you want to call the same proc in two different processes,
then you'd rather define the procedure in a SDL package, "use"
the package and call the procedure it in Process A and B.

I do not understand your requirement here. You could be a little
more specific as to what you want to acheive. In SDL, a procedure
can be used for doing a lot of things. Infact they can also have
states (which means that you can send signals to that state m/c,
have tasks in it, return variables etc.). On the other hand using
a signal is probably the simplest way to communicate between two
processes (There are several other ways also).

IIRR, you were using Telelogic Tau (from ur prev mail), If the
idea is to use the C micro code generator for your system then
there are a few restrictions (like no states in procedures etc.)

I am not sure if this is even a wee bit close to what you wanted
to know, but precise info on your problem will get you more help.
