Is this a bug?

It errors saying that I have passed a Floating Point as the first parameter.
Yet It is clearly not a floating point.
Is this a problem with ComTools failing to determine the data type correctly, or is FoxPro setting is wrong?
Wrapping it in an INT() like the error message suggests does work, but I fail to understand why it fails in the first place.

Any Ideas?
(Added Note: Also does the same under VFP 6 and 7 using CVF50.fll)


SET LIBRARY TO CTFW
PRIVATE a_tmp
DIMENSION a_tmp[3]
a_tmp[1]= 0.00
a_tmp[2]= ""
a_tmp[3]= 0

CREATE CURSOR Temp (n1 N(5,2), c1 C(5), n2 N(1))
INSERT INTO Temp VALUES (1.00, "Test", 3)

SELECT n1, c1, n2;
FROM Temp ;
INTO ARRAY a_tmp

?a_tmp[1]
?a_tmp[2]
?a_tmp[3]
? OR(a_tmp[3], 0)
