Description

This parameter reports the operating system under which Model 204 is running.

Valid settings of OPSYS are:

SettingMeaning
X'800000' Obsolete bit; ignore.
X'400000' z/OS (any version). Bit is set whenever environment is z/OS.
X'200000' IUCV communication available and in use.
X'100000' z/OS supports real 64-bit storage.
X'020000' 64-bit virtual storage is supported.
X'008000' z/VSE operating system
X'004000' z/VSE 370 support
X'002000' z/VSE 31-bit addressing supported
X'001000' z/VM (any version). Bit is set whenever environment is z/VM. z/VM Release 7 or earlier, if not combined with X'000400'.
X'000800' z/OS/ESA (z/OS SP2 or later). This option can be summed with X'400000'.
X'000400'z/VM/ESA (CMS Release 8 or later). This option can be summed with X'001000'.
X'000200' Fujitsu FACOM OSIV, F4 Edition, 40 OS.
X'000100' Large data sets are supported.
X'000080' Maintains the Breaking Event Address Register (BEAR), making its stored value available to Model 204 debugging code. The BEAR, available on z9 or higher systems, stores the address of a breaking event in CPU sequential processing, such as a branch.
X'000040' EAV volumes supported.
X'000020' 1 MB pages are supported.
X'000008' I/O from 64-bit virtual storage areas is supported.
X'000004' I/O from 64-bit virtual storage areas is supported for FBA devices.
X'000002' zHPF is supported.
