Using RDFCOM Interactively
The right-bracket (]) prompt indicates that RDFCOM is ready to accept your first
command. When you enter this command, RDFCOM processes it and then displays
another right-bracket prompt for your next command. You continue interacting with
RDFCOM in this way, repeatedly receiving a prompt and entering a command, until you
explicitly end the session.
You can also group two or more commands on an entry line, separated by semicolons.
The next example shows the INFO RDF and HISTORY commands entered in this way:
]INFO RDF; HISTORY
If it detects an error during startup, RDFCOM displays an error message between the
product banner and the right-bracket prompt. If it discovers an error in an RDFCOM
command, RDFCOM displays an error message immediately following the command.
Each error message line begins with the following text, even if the message continues to
more than one line:
*** Error ***
For example, if you issue an ADD RDF command without previously initializing RDF,
RDFCOM issues the following message:
*** Error *** RDF has not been initialized
Ending a Session
When you want to end your session with RDFCOM, you can either issue the EXIT
command or type Ctrl-Y.
Interrupting Command Processing
You can interrupt RDFCOM processing by pressing the BREAK key at your terminal.
RDFCOM responds as follows:
•
If you press BREAK at the RDFCOM input prompt (]), RDFCOM returns control of
the terminal to RDFCOM’s parent process (typically, TACL) but continues
execution. You can resume communication with RDFCOM by entering the
operating system command PAUSE at the TACL prompt.
•
If you press BREAK when an RDFCOM command that displays information (such
as STATUS RDF) is in progress, RDFCOM terminates execution of this command
and prompts you for another one.
Note. On most terminals, you enter Ctrl-Y by simultaneously pressing the control key and the
Y key. On some terminals, however, this escape function might be selected by a different key
combination or a single key. Before using RDFCOM, identify how this function is selected on
your terminal.
