>>>In a multiuser environment, it is difficult to use PACK to remove a deleted record. To work around this problem, we can recycle the deleted records. In that case, we do not need to physically remove those deleted records. But in VFP if the table has primary index the deleted records will have a problem with the "uniqueness". I wonder whether there is a simple way to work around it.

Thank you for your response. I have a further question here. When you try to recycle a deleted record, you need to locate deleted(). Will it be difficult when the table is huge?
