See http://www-1.ibm.com/servers/eserver/zseries/zos/bkserv/

More specifically, from that url click "v1r4" under PDFs, and then
click 'MVS'. This puts you here:

http://www-1.ibm.com/servers/eserver/zseries/zos/bkserv/r4pdf/mvs.html

The really interesting bits are in the Principals of Operation. Don't call
it a "POO", call it the "PoP". 

The High Level Assembler (HLASM) docs may be useful as well:

http://www-1.ibm.com/servers/eserver/zseries/zos/bkserv/r4pdf/hlasm.html

Also, there is an HLASM page with yet more stuff. 


IBM is really really good at documentation. They may implement something
so amazingly stupid it makes you slap your forehead, but darn if they
don't document what they did.
