Did you mean to make a data-type that was a 1-byte integer followed by a 4-byte integer with field names of 'a' and 'f4'? Perhaps you meant: dtype([('a','f4'),('b','i4')]) which is a 4-byte float followed by a 4-byte integer. -Travis ------------------------------------------------------------------------- Using Tomcat but need to do more?
