 Dear Henry (and others):

Thanks for clarifying this point...Here ! Here !

IT WAS A JOKE...the evils of "del" and all - one of Jim O'Neil's pet
peeves -

I ALWAYS write and say DELTA- even if after severals years it would save
me a few minutes by saying del.  Sorry for the fuss.

Still struggling with values and compositions and enriched and heavy,
etc... :-)

Scott
