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 MAX(draw.drawlstchg) FROM draw ;
	WHERE draw.obligor + draw.obligation + draw.unit = ;
	m.obligor + m.obligation + m.unit ;
	INTO ARRAY dchg
IF _tally > 0
	m.dlstchg = dchg[1]
ELSE
	m.dlstchg = {  /  /  }
ENDIF
