UDBCTL file-spec The UDBCTL file-spec command associates a user database (UDB) identifier with a file
name or a pair of file names. A UDB or UDB pair is a file or a pair of related files,
respectively, opened using the UDBCTL OPEN command; NCL works with UDBs and
UDB pairs. Entry-sequenced files, key-sequenced files, edit files, and Guardian
processes are all regarded as UDBs by NCL. You can open only key-sequenced files in
a UDB pair.
You can use this command if you did not assign a UDB ID to a file or a pair of files
when it was opened, and you now want to make the UDB or UDB pair available to
NCL. You can use this command to assign a new UDB ID to a UDB or UDB pair after
a UDBCTL STOP command.

file-name
file-spec
specifies the name of the file with which a UDB ID is associated. If you opened the
file as a single file, you must assign the UDB ID to the single file; you cannot
assign the UDB ID to the file as part of a pair of files.
(

file-spec
)
specifies the names of a pair of files with which a UDB ID is associated. If you
opened the two files as a pair, you must assign the UDB ID to the two files as a
pair; you cannot assign UDB IDs to the files individually.
udb-id
specifies a UDB ID for the UDB or UDB pair. You can specify a UDB ID from one
through eight characters long, beginning with a character other than a digit. The
UDBCTL OPEN command lists valid characters.

The default authority level of this command is 3.
