Dear Jamie.

Thank for the great feedback, it's always very valuable to get this kind 
of information when developing a completely new system.

Is it somehow posible to get hold of the data you have created both with 
the original programs and those converted by using the cores system. It 
will greatly help the debugging process, especially if you can provide 
some sort of "result" list, i.e. the name of the fields, types, number 
of records, special records, etc.

Kind regards,
Torsten Bonde Christiansen.
Software Developer, EpiData.
