Is there a limitation to the length of a SQL statement that the view designer generates?

With the view designer I created a SQL statement which has
the following where clause:

SELECT ...
WHERE Orders.dueon >= ?ldStartDate;
AND Orders.dueon <= ?ldEndDate;
AND Itmlayer.thickness = ?lcThickness;
AND Itmlayer.color = ?lcColor;
AND Itmlayer.process = ?lcProcess1;
OR (Itmlayer.process = ?lcProcess2);
OR (Itmlayer.process = ?lcProcess3);
OR (Itmlayer.process = ?lcProcess4)

However if I view the SQL it displays:

SELECT ...
WHERE Orders.dueon >= ?ldStartDate;
AND Orders.dueon <= ?ldEndDate;
AND Itmlayer.thickness = ?lcThickness;
AND Itmlayer.color = ?lcColor;
AND Itmlayer.process = ?lcProcess1;
OR (Itmlayer.process = ?lcProcess2);
OR (
and when I run this query it says that I'm missing a ")". I'm not, VFP is the one truncating my SQL!

Also, the way it puts in the parens is not what I wanted.
The desired SQL is:
SELECT ...
WHERE Orders.dueon >= ?ldStartDate;
AND Orders.dueon <= ?ldEndDate;
AND Itmlayer.thickness = ?lcThickness;
AND Itmlayer.color = ?lcColor;
AND ((Itmlayer.process = ?lcProcess1);
OR (Itmlayer.process = ?lcProcess2);
OR (Itmlayer.process = ?lcProcess3);
OR (Itmlayer.process = ?lcProcess4))

How does one do this using the View Designer?

Why doesn't VFP let me modify the SQL directly?
