I'll devise something (better?) to replace them.

Yes, of course - the pointer assignment does that.

With respect to the passing of a procedure reference as an assignment;
I meant to track that through to find out what the actual and dummy
argument symbols have that permit them to function correctly.  The
actual argument is a variable expression and yet it gets handled
correctly.  It's easier on the "little grey cells" to follow the front
end and copy that - although, doing it from first principles is more
virtuous!

I'll take a look at this a bit later on today.

Cheers

Paul
