Import Function on Version 5.

To MathGroup and Bob Hanlon,

My description of the problem was incorrect. It appears that the problem
lies in how

Import works in Version 5.1. Examples are;

1 - Import of the data.csv files in 5.01 using
ConversionOptions->{"Numeric"->False} works fine, but when I run it on 5.1 I
do not get the same formatted data records. It should bea dimensioned
14000x4 instead it

is dimensioned ilformed as 14000, without it all being strings. 2 - This
will cause Intersection of the common index not to work because I cannot use
data[[All,1]]. 3 - Has there been a Version 5.1 change in the Import
function and wher do I get the details?

Happy Holidays

$Version

5.1 for Mac OS X (October 25, 2004)

Intersection[{a,b,c,d},{a,d,e,f}]

{a, d}

Works fine.
