z/OS Compatibility

Our programs are working in any zOS environment without known problems. Our products are not dependent on any OS/390 or zOS release level. We are using documented standard interfaces like LE370, DB2, RACF, OPC PIF, TCP/IP, VSAM, BSAM, QSAM etc, IBM guarantees compatibility of these subsystems. Our programs are running in 31BIT mode, they have no awareness of the amount of real storage available. Therefore, we expect that our programs run without any consideration for the increased storage available to z/OS on a z900 or z800. z/OS is tri-modal. Even when a z/OS system is running in 64-bit mode, customers can still run existing AMODE=24 and AMODE=31 applications without having to relink or recompile them. Although our programs do not support 64-bit addresses, customers may get some of the benefits of 64-bit z/OS just by moving to it. With a 64-bit addressable real memory backing virtual memory, there will be less paging and swapping and, therefore, the possibility of better system performance. Actual results obtained in specific operating systems environments will vary depending on individual configurations and workload conditions.

Using JES2 z2 Mode

HORIZONT applications don't process the job number from the JES JOBID. The JES JOBID is used only as char(8) field. Both JES modes, R4 mode and z2 mode, can be used.
