Hi everybody, In my original question I had asked about the maximum number of fields in an AV32 ASCII TXT-table. There still isn't a definite answer. Some were suggesting to try it out which I had done with 1024 fields and it worked. ESRI-Germany also replied that they couldn't find any maximum numbers but had tested it for 3280 fields which had worked. Lars Mietzner suggested to use Access DBMS instead. Thanks also to Volker Rautenberg and Alejandra Episcopo.
