>The problem is the following code. In VFP6 it returns _tally = 0, in VFP9 it returns _tally = 1 with .NULL. in dchg[1]. What can I do about the _tally? There was not a match found in the DRAW but _TALLY returns a 1 and puts .NULL. in the array. Why does this happen and what can I do about it?

SELECT NVL(MAX(draw.drawlstchg),{}) FROM draw ;
	WHERE draw.obligor + draw.obligation + draw.unit = ;
	m.obligor + m.obligation + m.unit ;
	INTO ARRAY dchg
