Try this,Jordan. Since the fyknot's are global macro variables, you can not
reference them the way that data step array is referenced. But you can use
a macro array in a macro definiton within a loop, then call macro in data
setp,
or you can reference them one by one in open code.

%macro data;
   array X{5};
    %do i=1 %to 5;
           x{&i}=&&fyknot&i;
        %end;
  output;
%mend data;

data two;
       %data
run;
