Hello

I can't comment on the validity of the approach you're taking here (I
don't even know what "PHREG" is) - someone else will do that - but
here's some code that will do what you're looking to do.  If you run
this as is, you'll see in the log all the combinations of your
variables, each of which will correspond to a single call to the phreg
routine.  Good luck making sense of the results!

%macro myphregmacro(sample=,p_c=,delta=,seed=);
  %*<your phreg code here, using '&sample' '&p_c' '&delta' and '&seed'
in place of values>;
  %put &sample &delta &p_c &seed;
%mend;

data _null_;
  array mysamplesize(3) (60 120 180);
  array myp_c(5) (0.0 0.4 0.6 0.8 1.0);
  array mydelta(7) (0.5 0.8 1.0 1.2 1.5 1.8 2.0);
  array myseed(3) (539 259 59);
  do s=1 to dim(mysamplesize);
    do p=1 to dim(myp_c);
      do d=1 to dim(mydelta);
        do se=1 to dim(myseed);
          call execute('%MYPHREGMACRO(sample='||
mysamplesize(s)||',p_c='||myp_c(p)||',delta='||mydelta(d)||',seed='||
myseed(se)||')');
        end;
      end;
    end;
  end;
run;
