There is sure is. If you are talking about the fields of a table, there is a fields collection, which contains field objects. You can check out the help topics on Field Collection and Field Object.
If you give me a bit more detail I would be happy to help. Where do you want to do this? Are you talking about fields in a table or fields on a form?
I am taking a long weekend, though, so I won't be checking my email notification until Tuesday. Kathryn
