Joe,

I'm can't recall the specifics of Ian's argument but, based on the same
logic, can SCL do what a macro similar to the one he proposed can do?  For
example, in a non-scl data step, can it accomplish something like the
following?

libname test 'c:\';

*build test data;
data test.file1;
  input x;
  cards;
1
2
;
run;
data test.file2;
  input x;
  cards;
3
4
;
run;
data test.file3;
  input x;
  cards;
5
6
;
run;

%macro mklist(pref,from,to) ;
  %local i ret ;
  %do i = &from %to &to ;
    %let ret = &ret &pref&i;
  %end ;
  &ret
%mend  mklist ;

data one;
  set %mklist(test.file,1,3);
run;

Just curious,
Art
