To load the data into the restructured file, you must use an Enform FIND query to
correctly load the new file. The Enform FIND query creates an unstructured file that
you must FUP LOAD into the new file. In Enform, you must assign a unique name to
the new file, and the definitions of the old file as well as of the new file must be
available for Enform. The Enform User’s Guide describes how to use FIND.
Modifying NonStop SQL
Tables
To modify a NonStop SQL table that is used in an installed application, follow these
steps:
1. Change the NonStop SQL DDL source code file.
2. Use SQLCI to update the table.
3. Update any requester that will use the changed portion of the table (if applicable).
a. Update the requester’s Requester Context.
b. Add help text and video attribute information on the Display Detail screen.
4. Modify the custom service code of any service that refers to the changed portion of
the modified table.
5. Regenerate modified requesters and any server that contains a modified service.
If you plan to use Enscribe DDL for IPCs instead of sending a entire row from a table,
follow these steps:
1. Create a DDL source file for the IPC definition.
2. Use the DDL compiler to enter the definition into the DDL dictionary.
3. Update the requester context of the requester that will receive this IPC message.
4. Update the requester’s SEND Parameter Definition screen.
5. Regenerate the requester.
6. Update the IPC Definition screen of the service.
7. Regenerate any server that contains the modified service.
