Edit/Code Table Handling with the TABNULL Parameter

You can eliminate the duplication of values when migrating edit and code tables by using the new TABNULL parameter of the USMCPARM macro and regenerating your USMTPARM options module.

Setting the value of the TABNULL parameter to Y (Yes) adds the EXCLUDE VALUES NULL clause to edit and code table syntax. Using this clause removes existing table values before the new set of values are inserted. Not removing existing table values may duplicate the values if tables already exist in the target dictionary.

For more information about creating a tailored USMTPARM module, see the comments available in the installed version of your module.
