Subject:      Re: Data step Do loop to change the value of Macro Variable

1.e.g.

Thank you for the solution.

data mat2345;
  array x[2,3,4,5] x1-x120;
  retain n 0;
  do i=1 to 2;
    do j=1 to 3;
      do k=1 to 4;
        do l=1 to 5;
          n+1;
          ...
          x[i,j,k,l]=lag&n.(n);
          output;
        end;
      end;
    end;
  end;
run;

If array can help me identify a variable easily,then how to treat lag
function with macro variable?

2.What I want to do/get:
1)generate a series of variables.
2)put the value of a variable to macro varibles which can be used in new
created varible's name.
3)lag&n.(x) in a loop without %do loop
