User name SYSADMIN runs the product of KEYJOINF to allow the management of user accounts. User environments come from the KEYDEVF factory.

KEYJOINF a User/System administrator

KEYJOINF(0;sb,m,sb,keysdir ==>c;zmk,dirnode,fakeuser.) - build and run an administrator.
KEYSDIR is a directory of keys which KeyJOIN may hand out to users. See System Administrators Reference Manual (KL085) for suggested contents. SYS. and ADDLUDKY must be present. All else is optional.

ZMK is a Zapper key that can be added to the LUD to allow logon to this administator. Administrators can join sub administrators. (Done by KeyJOIN)

DIRNODE is the DIRUSER node documented in KL085. This key is added to a DIRUSER record collection. (Done by KeyJOIN)

FAKEUSER. is a copy of all the keys given and produced by KEYJOIN for its clients. This is returned so that KeyJOIN logic is the same for administrators as for other environments. see (keydevf) for a description of how this is used by KEYJOIN.

KEYJOINF(1;sb,m,sb,keysdir,dirnode ==>c) - add contents of keysdir to keys available to hand out

KEYJOINF(2;sb,m,sb,NODE ==>c;zmk,dirnode,fakeuser.) - build a new administrator for the clients represented by NODE (an internal node key in KEYJOIN). This is used ONLY by KEYJOIN itself.

KEYDEVF(0;sb,m,sb,keysdir ==>zmk,dirnode,user.) - build a standard user environment.
KEYSDIR is a directory of keys to give to the new environment (in its user.). It must include SYS. but nothing else is required.

DIRNODE is the returned DIRUSER node (see KL085). KEYJOIN adds this key to a DIRUSER database that is kept for debugging purposes.

ZMK is the zapper that should be added to a LUD if this user is allowed to logon to the system.

USER. is the user's USER. directory and contains some keys added by KEYDEVF. KEYJOIN adds the LUD control key and the ZMK key to USER. and makes no other use of this key. The initial contents of a USER. is below.

ZMK - the zapper (put into USER. by KEYJOIN)

LUDCONTROL - the ludcontrol key for this user (put into USER. by KEYJOIN)

SWITCHCMD - the key to set the default command system for the user (put into USER. by KEYDEVF)

ADMIN. - if the user was joined with the SYSMAINT option, this user is designated as a maintenance id for the joining administrator. ADMIN. contains the required power keys to do any maintenance for the clients of the administrator. This key is not present if the SYSMAINT option is not specified.

AUDIT - a key to the AUDIT file for the administrator (all rights but delete)

DIRUSER - a Read/Only key to the DIRUSER record collection for this administrator. See KL0085 for a description of its contents.

METMON - the meter monitor key for this set of users.

Other Keys as selected on the JOIN request. NOTE the SYSMAINT option gives the user ALL keys possible AND the key to SYSTEMVIEW. and USERVIEW. are RW keys rather than the usual R/O keys given when SYSTEMVIEW. or USERVIEW. is specified explicitly.

KEYDEVF(1;sb,m,sb,dirnode,keysdir ==>c) - add keys to user.
The keys in keysdir are added to the user's user.

KEYDEVF(2;sb,m,sb,dirnode ==>c;zmk,dirnode,user.) - replace the context switcher for the user.
