STATUS
Privilege Class: G
Use STORE STATUS to store selected virtual machine data in certain low storage
locations, simulating the hardware store status facility. These locations are
permanently assigned locations in guest absolute storage.
The STATUS operand causes the following data to be stored in low storage at the
guest absolute addresses shown:
Table 21. Non-z/Architecture mode guest
Address
Dec Hex
Length Content
163 A3 1 Architectural-mode id (X'00')
212 D4 4 Extended save area address. See note below.
216 D8 8 CPU timer
224 E0 8 Clock comparator
256 100 8 Current PSW
264 108 4 Prefix register
288 120 64 Access registers 0 through 15
352 160 32 Floating-point registers 0, 2, 4, 6
384 180 64 General registers 0 through 15
448 1C0 64 Control registers 0 through 15
Note: The extended save area address is saved only if floating-point extensions
are installed. When the extended save area is available, the virtual
machine’s floating-point registers 0 through 15 and floating-point control
register are stored there.
