Hi both - thanks Dan for your speedy reply - I tried the cats function
but it just gave me RR1, RR2, RR3 and not the value of those variables
as I was after.

Jim, the array worked a treat thanks. I've left out the macro but I
still don't know why it didn't work. To elaborate on the rest of the
datastep I've got it below but yes, &var &var.M and &var.U are meant
to go to HR HRM and HRU respectively. The dataset I'm working on is
verticalised so the variable going into the select statement (QNAME)
has the HR et al. values in it...

%macro group(var, var2, var3,var4) ;
    when ("&var") do i=1 to 3 ;
                      if qseq=i then qtext=g(&var4,i) ;
                    end ;
    when ("&var.M") qtext=&var2 ; *qtext should equal the value found
in the hrtavg variable ;
    when ("&var.U") qtext=&var3 ; *qtext should equal 83 ;
%mend group ;

data _2 ;
  set _1 ;
  select (qname) ;
    array g[7,3] hr1-hr3 rr1-rr3 ss1-ss3 tt1-tt3 uu1-uu3 vv1-vv3 ww1-
ww3 ; *(thanks!)
    /*...other when statements...*/
    %group(HR,hrtavg,83,1) ;
    %group(rr,rrm,8,2) ;
    *...;
    otherwise ;
  end ;
run ;
