Hi TideMan,
Thank you for your response.
Are these the coordinates of points in a plane? Yes
Why are there a variable number of points in each row? Coordinates in one row belongs to one curve.
Does each row represent a curve on the plane? Yes
Based on this please guide me.
Thanks,
Shaw.

well...
since your example does neither show six rows nor six columns, there's no more help at this point...
