The specified USERID could not be found.
The password specified in the fixed-length area of
the parameter list does not match the current pass­
word of the USERID being updated.
The value specified for the virtual machine storage
size or for the maximum virtual machine storage
size is too large. The maximum allowable size is 16
megabytes.
The value specified for the virtual machine storage
size or for the maximum virtual machine storage
size contains a syntax error or an invalid character.
The specified privilege classes are invalid.
The specified privilege classes contain a syntax
error or an invalid character.
The specified priority contains a syntax error or an
invalid character.
The priority value is too large. The maximum
allowable value is 99.
Parameter list size error; if return code = 65, the
list exceeds 112 bytes; if return code = 66, the list
size is less than zero bytes long.
A specified option is invalid. The invalid options
are VMSA VE, STFIRST, 370E, and MAXCONN nnnnn.
The value X'FFFFFFFF' was not coded after the
list of options.
The option value contains a syntax error or an
invalid character.
The parameter list contains an invalid minidisk
address.
The parameter list specifies an invalid access mode
for a minidisk.
The minidisk read, write, or multiple password
specified in the parameter list requires a change in

DIAGNOSE Code X'8C' --Access Certain Device Dependent Information Privilege' class G
DIAGNOSE X'8C' allows a virtual machine to obtain certain device-dependent
information without issuing a WRITE STRUCTURE FIELD QUERY REPLY. DIAGNOSE X'8C' retrieves this information from the RDEVBLOK or NICBLOK and creates a diagnose interface to enable the virtual machine to access it. Because
the information is obtained only at power-on time, if the characteristics of the ter­
minal are altered dynamically, those changes are not reflected in the data returned
by DIAGNOSE X'8C'. If a NETWORK ENABLE is issued to a device with
advanced features and a NETWORK ATTACH is issued prior to turning on the
device, the advanced features are non-operational. The data returned by DIAG­ NOSE X'8C' reflects this status.
Note: Devices for which the write structure field is not applicable return all zeroes
from the DIAGNOSE X'8C'.
Entry Values: DIAGNOSE X'8C' is invoked as follows:
Rx is the address of user-provided data buffer
Ry is the length of user-provided data buffer
Rx + 1 is the virtual device address.
Specification Exception: If the length specified is negative, the virtual machine
receives a specification exception from CPo If the length specified is greater than 6,
the user receives six bytes of information and the Ry contains the residual count
(length specified minus 6).
The user receives a specification exception if • The length specified is negative • The virtual device address specified is invalid • The buffer address is not on a doubleword boundary.
The user receives an addressing exception if • An invalid buffer address is specified.
