In article <79dse1$ut4$1@nnrp1.dejanews.com>, I scribbled:

Aaaaugh, I blew this one too.  It didn't occur to me while I was reading
the text that "designate" had a technical meaning other than just being
an English word.  It's defined in 3.10(1), so "view designated by the
actual" actually means "the thing that the actual parameter points to."
That makes more sense.

I miss the cross-references that used to occur at the end of every section
in the Ada 83 manual.  Those references would have included the word
"designate", and that would have tipped me off that I would need to look
up what the word meant in this context.  Meanwhile, I'm 0 for 2, tripped up
both times on words beginning with "d".  Time to start boning up on some of
the other basic concepts of the language: declarative region, dispatching,
discriminant, dynamic binding . . .
