There are two other records in the dictionary that should be deleted, %PROTECT.SPEC% and %FIELDS%.
From the System Editor EXEC line, execute the following two commands:
Run DELETE_ROW 'DICT.TABLENAME','%PROTECT.SPEC%' |
Run DELETE_ROW 'DICT.TABLENAME','%FIELDS%' |
At this point the file has had all indexes removed. The deleted indexes can now be rebuilt safely, using the list that you made in the Finding the Indexes step.
