/*
**  SETP -- set parameter
**
**	Sets a parameter, to be later sent by 'call' to whomever.
**
**	Parameters:
**		type -- parameter type.
**			PV_STRING -- a string, 'len' is ignored.
**			PV_TUPLE -- a tuple of length 'len'.
**			PV_QTREE -- a query tree pointer, 'len'
**				is ignored.
**			PV_INT -- an integer, 'len' is ignored.
**		val -- the value (real value if PV_INT, pointer
**			otherwise).
**		len -- the length of the tuple in PV_TUPLE mode.
**
**	Returns:
**		none
**
**	Side Effects:
**		Adjusts Ctx.ctx_pc & Ctx.ctx_pv.
**
**	Trace Flags:
**		4.8 - 4.15
