I'm surprised nobody commented on this.

Actually, you generally use two instructions in the format:

  call   Dlay4

   :

Dlay4
  return

Now, you *could* use a "return" instruction at the end of some handy
subroutine, *but*, that would prevent you from doing:

   :
Dlay16
  call   Dlay8
Dlay8
  call   Dlay4
Dlay4
  return

Which is a really nifty (and neat-o) way of generating longer delays very
simply and with few instructions (although very long delays are not possible
because of the limitations of the PIC's Stack).
