If you are looking for data, chances are that it will be in a newer format and won't be available as csv. This Jd release is of interest to anyone who wants data from one of these newer formats. Use Jd to easily load the data into a Jd table, and then get the data from the table and work directly in J. *** read carefully if you are running a version previous to 4.43 Be careful switching to this version as tables used in this version will be marked damaged if used with a previous version!!! Read 4.43 notes carefully: https://code.jsoftware.com/wiki/Jd/Release Read 'Run Production': https://code.jsoftware.com/wiki/Jd/General The code simplification and performance improvement justified the extra caution required in moving to this release. If you don't use multiple systems at different maintenance levels accessing the same tables, this update should not be a problem. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
