I got this website while doing google search: http://www.users.cloud9.net/~bradmcc/ibmsongbook.html
At the bottom of the page there is an example MVS task management control block diagram and it says: *IBM* <http://www.users.cloud9.net/~bradmcc/ibmsongbook.html> Program Logic Manuals are full of diagrams like the one above (I apologize for the poor quality of the reproduction!). The diagrams show how system control information is stored in "control blocks", and how fields in a given control block point to other related control blocks. These diagrams help programmers and debuggers to find information about the system, for program development and debugging (*esp.* finding information in "core dumps"). I'm interested and just wonder what is 'program logic manual'? I know IBM has manuals named MVS Data Areas but they don't have diagrams. Thanks. -- Best Regards, Johnny Luo ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
