DICTN
The file security of the dictionary files is the default file security of whoever compiles
the DDL source that creates the dictionary.
Only one dictionary can be open at a time. If you use the DICT command when you
already have a dictionary open, the DDL compiler closes the current dictionary before
opening the specified dictionary.
After a DICT or DICTN command creates a dictionary, using DICT or DICTN to open
the dictionary has no effect on whether the dictionary is audited or not. Either
command can open the dictionary, but the audited state of the dictionary does not
change.
If an existing dictionary that you open with the DICT command is nonaudited, the DDL
compiler issues a warning message.
To open a dictionary on the volume $DATA and subvolume SALES, enter:
?DICT $data.sales
If there is no dictionary on $DATA.SALES, the DDL compiler creates and then opens
the dictionary.
To execute the DDL compiler interactively and then clear and open the dictionary on
the current subvolume, you can enter:
31>DDL
?DICT !
Alternatively, you can include the DICT command when you run the DDL compiler:
32>DDL DICT
You can create a dictionary either by using the DICT command or by running the
Pathmaker application systems generator. When you add a Pathmaker project, the
Pathmaker software creates a dictionary for you.
More than one user can write to a dictionary at the same time, whether the Pathmaker
tool or the DDL compiler created the dictionary.
DICTN
The DICTN command:
•
Creates and opens a nonaudited dictionary or opens an existing dictionary
•
Writes subsequent object definitions to the open dictionary
Caution. The TMF cannot monitor nonaudited files. The integrity of a nonaudited dictionary on
an audited disk might be jeopardized if corruptions of the disk occur.
