Many of the sources I have found are very mathematical in nature and difficult to understand. However, the Informix Guide to SQL Tutorial (Part No. 000-7028) Version 4.1, July 1991, Chapter 4 is a 39 page practical reference that is easy to understand. This may be a good starting point for an Informix programmer. Mike Petersen mgp@nwedim.att.com (708) 224-4838 AT&T Lisle, IL /*********************************************************************/
