One possible method of finding and re-deleting all deleted records:

     Save the file as-is, "just in case".

     Rebuild the freechain.

     Lookup to that file, use NUMRECS() to get the number of records in
     the file.  Then, repeatedly lookup-free and fill one of the fields
     with "~~~~~~~".  Continue until lookupname[@RN] is greater than the
     value of NUMRECS() that you saved above.  (That means you have found
     all free records in the file.)

     Run another report that selects all records with "~~~~~~~" in that
     field, and delete them.
