The system allocator creates 2 tables from SALO input files: the offline system allocator table (known as the SAL table) and the online program allocation table (PAT). There is an entry in each table for every allocated program. The TPF linkage editor uses the libraries to resolve external references (VCONS) in object modules. Because this process occurs in an offline environment, the SAL table is strictly an offline structure. The PAT is used online by Enter/Back routines. It contains the addresses of all E-type programs as well as other allocation information. The PAT resides in the core image restart area and is brought into main storage by IPLB. Some fields in each PAT entry are initialized by CTIN. There is a PAT in main storage and the core image restart (CIMR) area for each subsystem.
If you need to display allocation characteristics of E-type programs, use the ZDPAT command. If you need to change allocation characteristics of E-type programs, use the ZAPAT command. See TPF Operations for more information about the ZDPAT and ZAPAT commands.
