Depending on what you mean by selecting. When you read the tab record by record you can add it to a ADO dataset or what ever and do your selecting, if your selecting is SQL. If your selecting is on the GIS object you will have to write your own GIS algorithms. Generally what MITAB does is (1) writing a complete MI table, no update possible and (2) read a MI table. You can catch every information from the tab file(alphanumeric data and GIS objects coords).
