What is the proper procedure to cut a doorway through cinder block? The cinder block wall is an interior wall that I want to access through from one room to another? It is not a weight bearing wall.

The way I have seen, and also works. Draw out opening(Plumb and Level)
Drill hole at corners first, to locate corners on other side of wall.
Use Target Saw, Giant concrete saw. Cut Square as you can.

Yes stratmando is correct, if you are doing it yourself, go to a tool rental store and rent a concrete saw

Okay, Well then what do I do, I mean do I need to build a special header? Fill any areas (voids) with concrete? Box or frame in with 'green board'? Best way to attach frame to block to sides? Installing the door will not be a problem.
Thanks

Oh Yeah, Almost Forgot, Look at any recpticles on each side of opening, and other side of
Block wall. Should be able to tell if Electrical conduit or wiring, If so, Remove, Cut Opening,
Then reroute electrical around opening, Also if switch and or light needed, May be the time, Before installing Door.

You Most Likely Need To Install A Piece Of Angel Iron Above Your Cut, This Will Prevent The Block Above From Cracking Once You Cut Your Hole Out. The Way Everyone Is Describing To Cut This Door In Is The Best Way,
If Your Putting A Door In Just Make Sure You Have Enough Room To Install Some Nailers On The Sides And Top. Most Likely Youll Only Be Able To Use Some Treated 3/4 Boards.
