Disable " symbol
in [Mathematica]
|
From: michuco on 2 Aug 2010 07:03 Hi, I am reading files of mixed strings and numbers using Data1= Import["file","Table"] where I have something like A" A" A' which should yield "{A",A",A'}", instead, mathematica gives me "{A" A",A'}". Is there anyway that I can disable the double quote " sign so that mathematica doesn't take this as a string? Many thanks Michuco

Note that the list structure is still not what you expected: ImportString["A\" A\" A'", "Table", "TextDelimiters" -> {}] hth, albert
