Under the Header Lines branch, set Composite Header Line No. to 1 - 9 or type a number into the box.
Make a selection from the Composite Pattern list. If you select <auto>, the import code will scan for recognized delimiters and will parse the line accordingly.

double dWfixed = value(strW.GetToken(2, TAN)$);--- Shouldn't it be TAB? Create a temporary variable: get the value of the 2nd item that is separated by a TAB. It still worked, though... why?This is my typo, should be TAB. Here tab and space is treated equally, seems by design.
