RE_fn_Blob2() is a function, not a macro, so it doesn't need to be defined or
called with parentheses.

FYI, it is defined as:
  _________________________________________________________

  #declare RE_fn_Blob2 = function (RE_P0_Value, RE_P1_Blob)
  { select
    ( RE_P1_Blob - RE_P0_Value, 0,
      pow ((RE_P1_Blob - RE_P0_Value) / RE_P1_Blob, 2)
    )
  }
  _________________________________________________________
