i had the same problem a couple of times. when i remember right something
like this should work:

#while (defined(SplnFile))
  #read (SplnFile, value)
  #declare Rv[cnt-1] = value;
  #declare cnt = cnt + 1;
#end

where value is an undefined identifier.
can't test it in the moment. rendering... ;-)
Hope that helps
