Jimi,
Since you are creating the index in the Load and deleting in the UnLoad, no other program/form/process is going to use the index at all unless you pass the name of it to them. Because you have it open, any changes you make to the table will be reflected in the index. And if the internal cache is updated via the SET REFRESH setting, the index will be updated as well.

HTH.
