DELETEREC processor. To speed up deletion this routine uses a system routine called BATCH.INDEXING. This is documented in Technical Bulletin # 3 by Robert Madden Jr.
BATCH INDEXING is used to determine whether index updates are written immediately to disk, or whether they are buffered until either 5 seconds of no activity has elapsed or 1000 bytes of information have been accumulated in memory. Using this routine speed improvements of up to 100% updating indexes can be achieved. BATCH.INDEXING is called with two parameters, the first a flag, true to turn buffering on, false to turn it off. The second parameter is the file variable of the file to be buffered.
