Defining symbols

If a dump analysis subcommand needs a control block, it automatically locates the control block, validates it, and creates a definition for it in the symbol table and storage map of your current user dump directory.

When a subcommand creates a definition, it uses the symbol name in the following table. All numbers, n, are decimal numbers, except where specified differently.
Note:
  1. Most symbols are defined by IPCS only for SVC dumps.
  2. To provide acceptable performance, IPCS places definitions in the symbol table for a dump only upon demand. The z/OS MVS IPCS User's Guide describes how a data description (data-descr) parameter on a subcommand can cause dynamic definition of a symbol, if it did not exist in the symbol table.
  3. A function that accesses data for which an IPCS name exists (for example, an ASCB) does not always associate an IPCS symbol with that data.
  4. The symbol table is used only by IPCS. Note that many functions can be performed in a non-IPCS environment where the symbol table is not available.
