There may be a difference between _tally and reccount(): Visual FoxPro may simply decide it is more efficient to place a filter on an existing table, instead of copying it to a temporary table (cursor). In this case, _tally is safer.
You can force VFP to copy records to a temporary table, using the NOFILTER keyword.
