This message has been marked as the solution to the initial question of the thread.
PACK has always done a REINDEX - it has to.

This is because it physically eliminates records, thus changing the positions of records, rendering (old) record numbers in indexes invalid.

PACK actually copies (undeleted) records to a new temporary table, REINDEXes that new table, and deletes the old table and renames te temporary ones to the original nems.

I am asking because after packing a do a complete reindexing anyway, and now i am wondering if it is really nesessary.
