**
**	Parameters:
**		s -- source of bytes.
**		d -- destination of bytes.
**		l -- length of block to move.
**
**	Returns:
**		none.
**
**	Side Effects:
**		copies 's' to 'd' for 'l' bytes.
**
**	Notes:
**		This can be easily written in assembly language on
**		machines like VAXes if performance is needed.
