Is your concern the fact that the area is in 24 bit storage, or that it is only 24 bytes in length? The residency issue is because the storage is part of the FRR stack, which resides in the fetch protected area of the PSA. Because it is in the PSA, it is size constrained. However, nothing is stopping you from building a control block and populating it as needed and storing the address (24 bit, 31 bit or 64 bit) in part of the 24 byte area. Just keep in mind that all accesses, both read and write, must be done while in PSW Key 0 or the access will result in an abend. ============================================== Wayne Driscoll OMEGAMON DB2 L3 Support/Development wdrisco(at)us(dot)ibm(dot)com All opinions are mine, and do not represent IBM Corporation. ==============================================
