Sometimes, you might want to suspend the processing of DDE transactions. For example, you can suspend processing in order to analyze the data that already in the worksheet. Also, if many data transfers are occurring, temporarily stopping DDE transactions might improve the performance time of an analysis.
While links are globally stopped, Minitab discards any incoming data. If you append data rather than replacing it, you might lose incoming data while a link is stopped.
When a link is deleted, all existing queued requests are processed, but no new requests are added.
