Define a normal one line template. Select the field form the first line. Double click on the field. Click on the Advanced tab of the Field Properties dialog.
You can select options to end the field on a set line number, on the appearance of a blank line, on the end of left justification, or on none of the above. This last option will continue selecting data for the field until the next template (trap) occurs.
This will help you grab all 1, 2 or 3 lines into one field. If you need to grab the data into separate fields, you can either use the guru trap described elsewhere in this forum, or you can use Textline do create calculated fields in the Table window.
