Identifying the Dictionary

Clearing Internal Tables

The ?DICTIONARY command names a subvolume that contains your dictionary. It
also clears the internal table and reclaims table space. The ?DICTIONARY command
is the same as the DICTIONARY statement.
?DICTIONARY [ dict-subvol-name ]
dict-subvol-name
is the name of the subvolume where your dictionary files reside. Refer to the
GUARDIAN Operating System Programmer's Guide for information on specifying
Tandem file names.
The dictionary identified in a DICTIONARY command must be created by the Data
Definition Language compiler. ENFORM issues an error message if you attempt to
use a dictionary compiled with a version of DDL that is not current. You must then
recompile the dictionary with a current version. Refer to the Data Definition Language
(DDL) Reference Manual for more information about creating and compiling a
dictionary.
There are two ways to identify the location of the dictionary:
The volume and subvolume where the dictionary resides can be specified as a part
of the Command Interpreter ENFORM command. If none is specified, it is
assumed that the dictionary resides on the default volume and subvolume.
The DICTIONARY statement or ?DICTIONARY command can specify where the
dictionary resides. Either overrides the dictionary identified at the time of the
Command Interpreter ENFORM command. When a new dictionary is specified,
the old internal table is cleared.
Entering the ?DICTIONARY command without a volume and subvolume name is a
simple means of clearing the entire internal table, without changing the dictionary. To
clear only certain items of the internal table, refer to the CLOSE and DELINK
statements in Section 4. The items cleared by the ?DICTIONARY command are:
All record descriptions from previous OPEN statements
All previous linking relationships
All user variable, user aggregate, and user table definitions
All parameter definitions.
All information from AT END, AT START, FOOTING, SUBFOOTING, SUBTITLE,
and TITLE statements.
The ?DICTIONARY command does not change the value set for any option variable
(such as: @HEADING or @STATS).
