I have a lot of code of the form

you can use DrIFT to automatically create bar_u to update a field and bar_s to set a field. They also behave nicer than the built in syntax as they pass through constructors without the given field rather than return bottom. John -- John Meacham - ⑆repetae.net⑆john⑈
