Compiling the Dictionary Schema
Compiling the Dictionary Schema
Each DDQUERYS query begins with this statement:
?DICTIONARY $SYSTEM.DDL
The statement opens the dictionary on subvolume $SYSTEM.DDL. Before you can run
any query, you must create a dictionary describing the dictionary files on subvolume
$SYSTEM.DDL. You can create the dictionary on any volume that does not already
have a dictionary, but to conform to the Enform Plus query, you must create it on
subvolume $SYSTEM.DDL. You create the dictionary by compiling DDSCHEMA for
example:
13> DDL/IN $system.system.ddschema, OUT/ DICT $system.ddl
The preceding command creates a dictionary describing the 14 dictionary files on
$SYSTEM.DDL and suppresses the listing. You can, of course, get a listing at your
terminal or list DDSCHEMA on a printer. Depending on how your dictionary is
managed, you might be able to omit this step. If the dictionary is already compiled on
subvolume $SYSTEM.DDL, you need not recompile it.
The DDQUERYS queries contain the following command:
?ASSIGN QUERY-COMPILER-LISTING to $NULL
If you do not have a $NULL process on your system, or if you want to redirect this
output, you can remove or change this line.
