This thread has gotten a little off track, but some erroneous statements are
being made.

A run statement is necessary anytime that macro variable can be resolved
before a step boundary, i.e. another data/proc or a run.  For example, the
following title displays "This is a test".  Assuming you wanted the value
given to &macvar in the datastep to show up in the title, you need a RUN
statement on that datastep.
 
%let macvar = a test;
 
data temp;
  x = 'no test';
  call symput('macvar',x);
 
title "this is &macvar";
 
proc print;
run;
