Thank you very much, that worked fine, which is OK at least to test
the compiler.

If you know a quick way to inspect the stack pointer, rather than me
having to dig for it, I'll fix it with pleasure. Alternatively, if
you know where I ought to look, please point me there. Oh, yes,
please also explain what "and"ing off a few bits means, unless you
mean that by trimming the incoming stack pointer I'll get a reasonable
value for a private copy. That would make just about as much sense as
I can grasp.
Mind you, I presume the "C" runtime plays such a trick if you suggest
it, should I look at those sources and where are they, as specific as
you can be?

I can't test any of them, unfortunately, but I'll make a note of your
comments. It saddens me that we're losing scope like this, but it's
inevitable, I suppose.
Thanks again, Russ.
