8.12.3 Parameter
S/370
Use S/370 for OS/360, VM/370 and MVS 3.8.
ESA/390
Use ESA/390 for MVS/XA, MVS/ESA, OS/390, VM/ESA, VSE/ESA, Linux/390 and
ZZSA. zOS can be run until version 1.2 with ESA/390 mode without installed bimo-
dal feature or until version 1.4 if the bimodal feature is installed.
ESAME
Use ESAME (Enterprise System Architecture, Modal Extensions) for z/OS, z/VM,
z/VSE and z/Linux. The ESAME mode is equivalent to z/Archtecture mode at at
Architecture Level 2.
When ESAME is specified, the machine will always be IPL’ed in ESA/390 mode but
the system is capable of being switched into the z/Architecture mode after IPL. This
is handled automatically by all z/Architecture operating systems.
z/ARCH
Use z/ARCH for z/OS, z/VM, z/VSE and z/Linux. z/ARCH is similar to ESAME. The
z/Arch mode is equivalent to z/Architecture mode at Architecture Level 3.
ENABLE
Enable the specified facility. If no architecture mode is given as additional parame-
ter the facility is enabled for all architecture modes.
DISABLE
Disable the specified facility. If no architecture mode is given as additional parame-
ter the facility is disabled for all architecture modes.
facility
The name of the facility that has to be enabled, disabled or displayed. An overview
of all architecture facilities can be found in “
page
bitno
The bit number of the facility that has to be enabled or disabled. The format of bitno is
BITnn, e.g. “BIT44” (Bit 44 = PFPO Facility Bit). An overview of all architecture facilities
can be found in “
QUERY
Display the facility settings.
ALL
Specifies that all facilities have to be displayed.
