  10: **  SETP -- set parameter
  11: **
  12: **	Sets a parameter, to be later sent by 'call' to whomever.
  13: **
  14: **	Parameters:
  15: **		type -- parameter type.
  16: **			PV_STRING -- a string, 'len' is ignored.
  17: **			PV_TUPLE -- a tuple of length 'len'.
  18: **			PV_QTREE -- a query tree pointer, 'len'
  19: **				is ignored.
  20: **			PV_INT -- an integer, 'len' is ignored.
  21: **		val -- the value (real value if PV_INT, pointer
  22: **			otherwise).
  23: **		len -- the length of the tuple in PV_TUPLE mode.
  24: **
  25: **	Returns:
  26: **		none

  28: **	Side Effects:
  29: **		Adjusts Ctx.ctx_pc & Ctx.ctx_pv.
