Have a look at the guidance when posting questions, its next to the Post button.  Provide test data in the form of a datastep in a code window, and show required output.  As I am not typing that out, here is a best guess:

proc transpose data=other_data out=t_other prefix=rest;
  var var;
run;

data want;
  merge have t_other;
  array var{10};
  array rest{10};
  array res{10};
  do i=1 to 10;
    res{i}=var{i}-rest{i};
  end;
run;
