Dear Jamie, Thanks for the nice response to the query Random selection of records. It worked very well. Epi Analysis has far more features than EPI6 and the documentation is not that detailed. I had suggested to Jens once to get the manual written by the vast user base. Jens suggested to add to the how to section only. If you look at the questions, answers of the last few years (since the release of Epi Analysis) it is a huge database of good quality questions and answers. If these are classified and documented in the form of a pdf manual, it can save a lot of time of the friends at the epidata help desk. Of course detailed command reference (like that of EPI6) is our dream and together all of us users can make it happen. Once again I am thankful for the solution provided.
