Dear Keith,
Not being familiar myself with this subject I'm afraid I don't have an
answer for you, but I would like to mention that we are considering the
issue of context parameters in the SDL subset and one thing that has been
identified already is the need for these parameters to have any type, for
both blocks and processes.
As a procedure isn't a data-type and don't seem to be essential, this
aspect of context parameters may not be included.

Hello all
I hope that somebody is able to understand this question and also to help out.
I have process type with one signal as a context parameter. I would dearly like to have an integer number as a second parameter but that is not possible with process types. However procedures are a context parameter that can be used. I thought that I could use a procedure to return a different integer when called by different instances of the process. Everything seem hunky dory when I declare the procedure name parameter as 'win' and the instances of the procedure have winA and winB as the actual procedure parameter.
But I cannot seem to get IN/OUT bit right. I have an error message 'Error: I/OUT Parameter missing for procedure when it represents winA ( / win B)
A:Node The declaration in the process box
<PromptA,winA>
Proceedure WinA
FPAR Proceedure heading etc
IN/OUT n Integer
The body of the procedure just assigns an integer n=30.
The procedure call is just win.
Any suggests welcomed,.
Keith Moss
