Not a matter of quoting, but scope. A %let inside a macro is local to that
macro, so it's not in scope. You either need a %global statement beforehand
to bring it into global scope, or not to use a macro like that. You could
write the same macro as
%let specyr=2009;
%macro setwhere(specyr);
%if &SpecYr. ne %then "for &SpecYr. Specification Year.";
%else "for all Specification Years";
%mend setwhere;
%let SpecTitle = %setwhere(&specyr);
%put &spectitle;
for example, which moves the %let outside of the macro but doesn't create a
new global variable.
