Evidently some of the invisible quoting that
is embedded in the macro variables has a set
that has the NotResolved inference. e.g.


%let a=begin;

%let c=%str(&a);
%put >&c<;

%let b=%nrstr(&a);
%put >&b<;


%put UPCASE produces: %upcase(&a);
%put UPCASE produces: %upcase(&b);
%put QUPCASE produces: %qupcase(&b);


The tests above indicate that there are some
lingering NR connotations still embedded in the
text string for b but not for a.



Hope this is helpful.

I'm confused the result of the following little paragraph:

%let a=begin;
%let b=%nrstr(&a);
%put UPCASE produces: %upcase(&b);
%put QUPCASE produces: %qupcase(&b);

Result:
UPCASE produces:  begin
QUPCASE produces: &A

Why %upcase doesn't make 'begin' upcase? It seems that after it
interpret the resolved value-&a, it won't do anything else.

I'll appreciate any opinions!
