I am running a DB2 Cobol program that is calling an Assembler module which does things with 64 bit storage.
I am experiencing a U4036 abend with a reason code of 6 which tells me that there was a problem when in 64 bit mode.
No doubt, I am getting some kind of program check in my Assembler module. The problem that I am having is trying to get the PSW that will tell me where I am failing. The only messages that are coming out are those telling me that a dump was created. The IPCS LEDATA and SUMMARY commands are not giving me any additional information either.
Can anyone suggest how I might get the address of the failing instruction?
Assuming you have a complete dump there is a good chance that the information you are looking for can be found in the SYSTRACE option of IPCS.The system trace is a wrap around area and is used by the whole system so if the dump is taken too late it is possible that the data has already been overwritten
