The virtual storage for the program requesting the dump System data associated with the program. Each one dumps different areas. Select the dump that gives the areas needed for diagnosing your problem.
SNAP Dump Use a SNAP dump when testing a problem program.
A SNAP dump shows one or more areas of virtual storage that a program, while running, requests the system to dump. A series of SNAP dumps can show an area at different stages in order to picture a program's processing, dumping one or more fields repeatedly to let the programmer check intermediate steps in calculations. SNAP dumps are preformatted, you cannot use IPCS to format them. Note that a SNAP dump is written while a program runs, rather than during abnormal end. The system enters an instruction loop.
