The HEADING command causes the heading (first page) of a dump to be printed at the terminal or line printer.
The information provided in the header includes the title of the MCP, the cause of the memory dump, the name of the processor that initiated the dump, and the MCP RELEASEID.
For an enhanced memory dump, a title displaying “<machine type> <dump type> MEMORY DUMP” is shown. In this title, the machine type is the name of the machine, and the dump type can be COMPLETE, ALLINUSE, or PARTIAL.
