Running:

data vset;
          v1='1';v2='2';v3='3';v4='4';v5='5';
          run;

%let n = 5;

data reverse;
   set vset;
   call poke(reverse(peekc(addr(v1),&n)),addr(v1),&n);
 run;

copied directly from Charles Patridge's post with SAS V8.0 under Solaris 5.6
gives:

Obs    v1    v2    v3    v4    v5

 1     5     4     3     2     1

just as Paul claimed it would.  I cannot explain the discrepancy.
