But in this case, the initial LOCATE has a pause (it seems to be doing a rather slow search for the index, like it's considering the options, then zips to the record), and then subsequent CONTinues are instantaneous...and we're talking major table size here...well, I always use SEEKs programmatically anyway on these tables, so it's kind of moot that LOCATE may be a bit slower...
