REQUEST=LIST requests a list of objects be provided to the caller.
The requirements for the caller are:
| Environmental factor | Requirement |
|---|---|
| Minimum authorization: | Problem state and PSW key 8-15. The caller must be running in supervisor state or with PSW key 0-7 to use the following parameters:
The caller must be running in supervisor state or with PSW key 0-7 or have a PSW key that matches the storage key of the memory object to be cleared by DISCARDDATA. The caller must be running in supervisor state or with PSW key 0-7 to DETACH a memory object owned by another task. |
| Dispatchable unit mode: | Task or SRB. |
| Cross memory mode: | Any PASN, any HASN, any SASN. Note: The problem
state caller running in PSW key 8-15 can use GETSTOR/DETACH only when
the primary address space is the home address space.
|
| AMODE: | 31- or 64-bit. |
| ASC mode: | Primary or access register (AR) |
| Interrupt status: | Enabled for I/O and external interrupts |
| Locks: | A local lock may be held, subject to the following
limitation: When a local lock is held for a requests (GETSTOR, SHAREMEMOBJ, DETACH, or DISCARDDATA) for non-shared memory objects, the lock must be for the address space specified (or defaulted) by the input ALETVALUE. |
| Control parameters: | Control parameters must be in the primary address space and can reside both below and above the bar. |

This macro supports multiple versions. Some keywords are unique to certain versions. See PLISTVER parameter description.
Before issuing the IARV64 macro, the caller does not have to place any information into any register unless using it in register notation for a particular parameter, or using it as a base register.
Some callers depend on register contents remaining the same before and after issuing a service. If the system changes the contents of registers on which the caller depends, the caller must save them before issuing the service, and restore them after the system returns control.

The parameters are explained as follows:
The information is returned in a work area that you specify, in a format described in IAXV64WA. Information includes starting address, ending address, storage key and flags indicating if the memory object is shared or if it contains multiple guard areas.
To code: Specify the RS-type address, or address in register (2)-(12), of a pointer field.
To code: Specify the RS-type address, or address in register (2)-(12), of a fullword field.
An optional parameter that specifies whether the list request is for all allocated memory objects or for a subset of the allocated memory objects The default is V64SELECT=NO.
To code: Specify the RS-type address, or address in register (2)-(12), of an 8-character field.
To code: Specify the RS-type address of a fullword field, or register (2)-(12).
To code: Specify the RS-type address of a fullword field, or register (2)-(12).
If you can tolerate the size change, IBM® recommends that you always specify PLISTVER=MAX on the list form of the macro. Specifying MAX ensures that the list-form parameter list is always long enough to hold all the parameters you might specify on the execute form, when both are assembled with the same level of the system. In this way, MAX ensures that the parameter list does not overwrite nearby storage.
Use MF=S to specify the standard form of the macro, which builds an inline parameter list and generates the macro invocation to transfer control to the service. MF=S is the default.
Use MF=L to specify the list form of the macro. Use the list form together with the execute form of the macro for applications that require reentrant code. The list form defines an area of storage that the execute form uses to store the parameters. Only the PLISTVER parameter may be coded with the list form of the macro.
Use MF=E to specify the execute form of the macro. Use the execute form together with the list form of the macro for applications that require reentrant code. The execute form of the macro stores the parameters into the storage area defined by the list form, and generates the macro invocation to transfer control to the service.
