The document provides an overview of an IBM presentation focused on the RDz lunch and learn series for COBOL programmers, specifically delving into debugger capabilities. It mentions speakers, including IBM architects and developers, and outlines the agenda, which includes topics on debugging CICS and IMS applications. Additionally, it presents operational details regarding compiler options and the integrated debugger's functionality, along with a disclaimer about the confidentiality and future product directions.

Debug Manager (v9011)
 No IP address/port required in the application startup JCL
– Prevents problems where DHCP reassigns client IP addresses
– Once set up for debug, JCL doesn't need to be modified again
 The direction of the debug connection now matches direction of the
RSE connection
– No outbound connection from the z/OS host is required
– Avoids problems where the client machines are behind a router or NAT
 Uses RSE credentials to match a debug sessions to an appropriate UI
 Debug jobs will wait until an appropriate user connects through RSE
