title: How to Read IBM 4690 supermarket application file .DAT
body: <p>i have a <code>.DAT</code> file generated by <code>IBM 4690</code>  I'm unable to read it. Apparently it comes from the IBM 4690 Supermarket Application controller. I've done internet searches and nothing helpful comes up. The guy that sent it to me said he has never had to convert or read it into CSV or any other file format, so he can't provide any assistance. Can anyone help reading it using c# or any tool ?</p>
