  Hi Netland,
	I have a question for all you fellow techies.  I would like to
    create my own MsgPort via the Exec.  However, I want to do it in assembler
    I know that the CreatePort() function exists, but only in the link
    library. (ie. it's not a REAL rom routine.)  So, I am trying to get
    its equivalent.  I am currently doing something like the following:

     1) Allocate a hunk of memory MP_SIZE big.

     2) set the LN_NAME to point to my name.

     3) set the LN_PRI to 0

     4) Call AddPort()

     I >THINK< this is the correct way of going about it.  However I'm not
     sure, and I don't have an Exec manual handy for the source to
     CreatePort(), and this part of the code is a strong suspect for a
     bug that I have.

	What I'd like is one of the following:
	a) confirmation that this method is right,
	b) an example of how to do this (C or ASM), or
	c) source to CreatePort() from the Exec manual

     I really doubt c) is legal, so I'm not too concerned about that.  a)
     or b) would solve my problem just as well.   ANY help/suggestions
     would be appreciated!   E-mail or post, as you feel appropriate.

	  Thanks in advance,
		Greg Roberts II
