Can someone point me to a sample so I can get started? This will be my first Haskkel project, after reading about it for some months now. I need to extract text from a structed binary file. Its a local database for a commercial app of proprietary structure, though the structure has been determined. So I need to move along a number of bytes, take a few chunks of so many more bytes and grab the string and move on to the next record, dumping the contents - ultimately dumping it to XML. It'll need to run on windows so I guess I had better use Hugs. So a sample and any advice would be an excellent start for me, and would be greatly appreciated. Thanks Brian McQueen
