For accessing storage using 64-bit addresses and data spaces, you need to use the Storage Access function of the Symbol Service: z/OS V1R13.0 MVS IPCS Customization 10.2.17 Symbol Service The symbol service enables exit routines to process symbols and obtain data represented by the symbols. The symbol service differs from the get and equate symbol services by requiring callers to pass parameter list XSSP (mapped by mapping macro BLSRXSSP) that describes which symbol functions to use. For reasons of completeness and compatibility, some of the symbol service functions duplicate the functions provided by the equate symbol and get symbol services. The functions provided by the symbol service are: Equate Symbol This function adds the specified symbol to the dump directory. The symbol can be for a literal value. Get Symbol This function retrieves the equate symbol record (ESR) for the specified symbol. Storage Access This function accesses the storage requested in the equate symbol record that is passed as input. Validity check This function allows the user to request a validity check for a control block and the creation of an SA record (BLSRSASY macro). Check for Active TCB This function allows the user to determine if the task described by the passed equate symbol record was active at the time of dump. Checks for active tasks are only valid on a SADMP. Note that in OS/390 Release 10 and higher, the symbol service supports 64-bit addresses and lengths. Jim Mulder z/OS System Test IBM Corp.
