Catalogs, or enables, the user-defined commands (UDCs) in a
     specified catalog file at the user, account, or system level.
     You can also use this command to disable all UDCs on the system.


     If you enter the SETCATALOG command without specifying a catalog
file name, all UDCs are disabled (deleted from the UDC directory)
regardless of whether or not you use the ;DELETE option.

Use only MPE/iX flat files as UDC files. If you issue the
SETCATALOG command for any other type of file, you will get
unpredictable results.


SETCATALOG [catfilename[,catfilename,...[,catfilename]]]


catfilename The name of a file containing User Defined Commands
to be cataloged. Commands within the file must be
separated from each other by a line whose first
character is an asterisk (*).

SHOW Specifies a listing of the User Defined Commands as
the UDC files are cataloged. Error messages are
printed for command lines that contain any errors.
This parameter is useful for locating errors in UDC files.

ACCOUNT Specifies cataloging of the file at the account
level. Using this parameter requires Account
Manager (AM) capability.

SYSTEM Specifies cataloging of the file at the system
level. Using this parameter requires System Manager
(SM) capability.

USER Allows users who have AM capability to change the
UDC catalog set for users in their account. Users
having SM capabilities can change the UDC catalog
set for any user. This does not rebuild the
executing UDC Directory the user must log on after
the command has been invoked.

RESET Causes the file(s) being cataloged to replace all
files that are already cataloged. Thus, specifying
one or more files with SETCATALOG and using the
RESET option functions the way SETCATALOG did with
a list of one or more files in MPE V/E. RESET is
the default if no option is specified.

APPEND Permits the user to add UDCs to the Directory. This
option causes the file(s) being cataloged to be
appended to the existing catalog. It also finds and
makes adjustments for any logon UDCs if appropriate.

DELETE Deletes the file(s) from the existing UDC Directory.
This permits the user to delete individual files
from the catalog directory. The original order of
the catalog is maintained. It also finds and makes
adjustments for logon UDCs. The ACCOUNT and SYSTEM
options allow the user to delete the cataloged file
at the account or system levels. The default is
user level.


     The SETCATALOG command allows you to catalog user-defined
     commands.  You must have lock access and either read or execute
     access to the UDC file that you specify on the command line.

     When you set your own UDCs, the change takes place in your
     UDC catalog immediately.  If you specify ;ACCOUNT or
     ;SYSTEM, your UDC catalog is changed immediately, but other
     users in your account or system must log on again in order
     to have those changes available to them.

     If you set a UDC and specify another user (;USER=), that
     user must log on again in order to have the changes available.

     The ability to delete or append files is particularly useful
     because, although most UDC files do not change, new UDC
     commands are frequently added or modified.  Using ;DELETE
     and ;APPEND allows you to make changes without incurring the
     overhead of recataloging the entire Directory for every
     change.  Grouping UDC files into functions will further
     reduce the work involved in modifying UDCs.

     The RECURSION option now available in UDCs relieves the user
     of having to define a particular command more than once in a
     catalog set, and from having to maintain a particular order
     for commands within a catalog set.

     If SETCATALOG is used in a UDC, all valid commands through
     and including the SETCATALOG command will execute.  But
     execution of the UDC will terminate after the execution of
     the SETCATALOG command.  Commands that follow will not
     execute.  The SETCATALOG command does not have this effect
     when executed in a command file.

     You may invoke the SETCATALOG command only from the logon
     Command Interpreter (user main), where it is passed through the
     scanner/parser.  You cannot invoke SETCATALOG from
     any other program (any child process).

     This command is available in a session, job, or in
     Break.  It is not available from a program.  Pressing [Break] has
     no effect on this command.


     SETCATALOG udca; USER=john.workers

     This sets the UDC Directory for the user john.workers with
     the commands in the file named udca.  The USER option cannot
     be specified with the ACCOUNT or SYSTEM options.  Attempting
     to do so will produce an error.

     The following two command sequences are equivalent

     SETCATALOG udca, udcb

     SETCATALOG udca
     SETCATALOG udcb ;append

     In the first example, the command has an implied RESET, and
     thus overwrites the previous file set in the Directory.  In
     the second example, udca is entered into the Directory, and
     then udcb is appended to the Directory without affecting
     udca.  It also finds new logon commands if appropriate.

     SETCATALOG udca ;delete ;account

     This command deletes udca from the Directory at the account
     level, provided it was cataloged at the account level.  If
     other account level UDCs reside in the Directory along with
     udca, they remain undisturbed by this deletion.  When
     appropriate, a new logon UDC will be set up.


     It is not good practice to create UDCs that have the same name
as other files, especially command files or any other files your
users may confuse with UDCs. MPE/iX first interprets the file
name as a UDC and will attempt to execute it. For example, if
there is a UDC named COMM and a user enters
COMM.GROUP.ACCT at the CI prompt, MPE/iX will execute
the COMM UDC and pass .GROUP.ACCT as the first parameter.
