If you receive a system abend code, look up the code and the corresponding information in the publications for the system you are using.
When a system abend occurs, the operating system can generate a system dump. System dumps are written to ddname SYSMDUMP, SYSABEND, or SYSUDUMP. If the DYNDUMP runtime option is used in combination with the TERMTHDACT runtime option, the system dump can be written without the ddname specified. System dumps show the memory state at the time of the condition. See Generating a system dump for more information about system dumps.
