Hello, TeX users!

I'm relatively new user both of TeX and of usenet, so forgive me if
my question is FAQ, or this is not a right place to ask, etc...

I'm using ams-TeX, Version 2.1 running on SunOS UNIX. I know perfectly
well how to draw a commutative diagram of the shape

         * --> *
         |     |
         V     V
         * --> *

using \CD in math-mode. But drawing a diagram of the following shape:

         * --> * --> *
         |           |
         V           V
         * --------> *

seems to me as an unsolvable problem.

Any comments, suggestions,... would be greatly appreciated.
(Yes, I know that one possible to print something like

         * --> * --> *
         |     |     |
         V     V     V
         * --> *  =  *

but due to the large expressions involved in the diagram, this is not
a best solutions)

Sorry for my English, b.t.w. (I'm relatively new user of English too :-))
