Address Space TCB Structure

[esst...@juno.com]

.
Many Years ago I attended an MVS/XA structure and logic class.
.
In that class there were diagrams of the TCB Structure for Started Task, Batch 
Jobs, and TSO logon address space.
I'm talking about the address space TCB structure (Region Control Task, Dump 
Services, STC Control, etc.).
.
Are these diagrams available with z/OS. and if so where can I Find it ?
