Hello,

Supposing your file is tab-delimited,the following kind of works:

ReadList["EWZ2.TXT",
      {Number, Word, Word, Number, Number, Number, Number,
        Number}, WordSeparators -> "\t"]

Unfortunately the keyword "Word" means that you might have
to apply ToExpression to the second and third column, in case
you want to have "EWZ" and not EWZ, etc.

I thought that maybe "Expression" would do the trick, but it does not.
Maybe it is time that the good WRI-programmers improve the very
important
function ReadList.
Import is not good (fast) enough.
