But it appears that this is possible:

IF  A = X
  IF  B = Y 
    IF  C = Z
      DO THIS
    END-IF
    IF  D = Q
      DO THAT
    END-IF
  ELSE   (this is B NOT = Y)
    IF  K = M
      do the dew
    END-IF
  END-IF
END-IF.

Can you do this kind of nesting without using the END-IF?  If so, how?
