I have already been peeking in hex editors. I have picked out 80% of the data and been able to read it into perl (since posting this). However I have noticed some characters which appear to act as boundries between certain fields which are not in the standard ascii set, so I'll have trouble evaluating those in my code, I know how to do it in Quick Basic, I've never tried in perl.

The next big problem is that the most important data appears as gibberish. I think I will need to experiment with several data files and look for similarities and differences. I'm getting there though.

Ghex will show you what is in the file in hex and ascii format.

    I am a PAT tester and have found over my time in the role that the
    software is a total rip off! If you purchase a digital camera,
    scanner, webcam or anything else that interfaces with a PC you get
    the software to make it go. Spend £1,000 on a PAT tester and you are
    then expected to pay £300 on top just for the privilege of being
    able to download the data!

    The latest version of the software in question is even worse, it
    costs £109 + VAT annually! And of course it doesn't work on Linux. I
    have methods of accessing the basic data required but have just
    found out the latest and greatest machine I would love to have has
    several features which are only downloadable in their custom format
    which is not text readable. My machine has the old version of this
    custom format and the machine I would like uses a revised version. I
    am told it is very difficult to reverse engineer it.

    An example of the older file format is here:
    www.cliftonts.co.uk/SSS <http://www.cliftonts.co.uk/SSS>

    So my question is this, how does one go about accessing a file like
    this when they do not know the format? I have worked with text based
    files, CSV etc but never something which does not load in a text editor.

    Any assistance would be appreciated.

    Thanks
