any entry of the directory. The user
entry and may replace the following data: logon password virtual machine storage size maximum virtual machine storage size privilege classes dispatching priority logical editing symbols initial program load (IPL) system account number distribution word user options minidisk access mode minidisk read, write, or multiple password
with the exception of the account number, all changes to the entry
take effect the next time the USEBID associated with the entry logs onto VK/370. The account number may be updated such that the change (1)
takes effect immediately, (2) takes effect immediately but is temporary
lasting only until the USERID is logged off, or (3) takes effect the
next time the USEBID associated with the entry is logged on. DIAGNOSE Code X'84' cannot add new entries to the directory, cannot
delete existing entries, nor can it alter directory user-description
statements. It can only replace existing directory data. Data is
replaced in the form of the directory created by the directory service
program, that is, in VM/370 control blocks.
For a detailed description of the directory data, see the Rlanging Generation guide. When DIAGNOSE Code X'84' is issued, the Rx register must point to a
variable length parameter list and the Ry register must specify, in
bytes, the length of the list. The parameter list contains an area of
fixed length followed by an area of variable length. Data in the
fixed-length area identifies the directory entry to be updated, the
password of the USERID associated with the entry, and the data field to
be replaced in the directory entry. The variable-length area contains
replacement data for the directory entry. All entries in the parameter
list must contain unpacked, EBCDIC data. 206 IBM VM/370 System programmer's Guide

The parameter list is organized as follows: r-'-----. I USERID I 1 , password I fixed-length area 1 ----I I operation , , /
/ I ----I /
/ I L-- _____ USERI D
variable-length area
The USERID of the user whose directory entry will be updated. This
is an eight-character, left-justified value and must be padded with
blanks.
password
The current password of the USERID whose directory entry will be
updated. This is an eight-character, left-justified value and must
be padded with blanks.
operation
An eiqht-byte, left-justified character string that identifies the
data that is to be replaced in the directory entry. Valid values
and the data that each identifies for replacement are defined in
the description of the variable-length area which follows.
The following diagram shows for each value of the operation field,
(1) the data that must be in the variable-length area of the
parameter list, and (2) the format and characteristics of the data.
