Subject:      Macro help needed

This seems like it should be possible, but I am having no luck at getting the
following code to work.
 
The macro variables NTIME and NSITE are declared in the program above.  What I
have, is I have different data step type problems where I want to execute them
NTIMES to get NTIMES variables.  I have the macro loop set up, and as long as I
nest the code inside the loop, it works fine.  My goal though is to use a %LET
statement to re-assign what the loop does on the inside.  An example of the
code I have tried follows:
 
%let s=%nrstr(
  R&i=FR[((&i-1)*&NSITE))+1:&i*&NSITE, 1:&NSPECS];
  F&i=R&i`;
  );
 
%macro loop;
  %do i=1 %to &NTIME;
    &s
  %end;
%mend loop;
 
loop
 
I have tried several macro functions besides NRSTR, but none work.  The code
that follows the NRSTR function works when I put it in place of the &s.  But,
there are lots of 'things' that are generated with this particular loop, and
though it seems small, I would like not to have to type the macro loop over
and over again.  Any help would be greatly appreciated.  TIA.  Michele Marini
