Terminating a DNSCOM
Command or Session
If you use the BREAK key while a DNSCOM command is in progress, DNSCOM
terminates the command and returns a new prompt. Any update that may be in
progress is canceled.
To terminate a DNSCOM session, use the EXIT command. CRTL-Y also terminates a
DNSCOM session.
Entering Multiple
Commands on a Single
Line
To enter more than one DNSCOM command on the same line, separate each command
with a semicolon (;). If an error occurs in one of the stacked commands, the
remaining commands are not executed.
Examples:
DNSCOM LIST * ON \MEMPHIS AT $RDNS; INFO TENNESSEE
DNSCOM DELETE SS * AT \OSAKA; INFO SS PATHWAY AT \TOKYO
Entering a Command on
More Than One Line
To continue a DNSCOM command over multiple lines, use the ampersand (&) as the
continuation character. As many as 1024 characters are allowed in a continued
command; however, the FC command can handle no more than 132 characters.
Examples:
ADD COMPOSITETYPE ATM, COMPONENTS (LU, TERM, TASK), OWNER &
EZCORP, TYPENUM 1
ALTER DNS AT \NEWYORK.$DNS.RDSDNS.DNSCONF, MAXEXPORTS 4, &
EXPORTDELAY 30
When to Use the AT, IN,
ON, UNDER, and USING
Phrases
Since there are a lot of keywords in the DNSCOM syntax to keep track of, the
following list indicates when to use the key phrases that begin with AT, IN, ON,
UNDER, or USING.
AT specifies a name manager or configuration file to be used in processing the
command or phrase where AT appears.
When AT is followed by a system name, for instance, STATUS DNS AT
\HOUSTON, that system name is combined with the current manager name to
form the name of the DNS manager request.
If AT is followed by a process name in local format, the current CMDSYS setting is
applied to the name to produce the name of the name manager, such as in the
command SET LIKE FOO AT $DNS4.
AT can be followed by the name of a configuration file, such as in the command
INFO DNS AT $DATA.DNS.CONFIG. See “Switching DNS Configurations”
earlier in this section for more information about using AT with configuration file
names.
