code: public BaseField getField(String strTableName, int iFieldSeq)   // Lookup this field
      {
          Record record = this.getRecord(strTableName);
          if (record != null)
              return record.getField(iFieldSeq);
          return null;    // Not found
      }
docs: Get this field in the record.
  This is a little different for a query record, because I have to look through multiple records.
  @param iFieldSeq The position in the query to retrive.
  @param strTableName The record name.
  @return The field at this location.
