Limits on text typed in fields

[Kristen.Billings at med.va.gov]

I am working on a program that requires users to type answers into fields,
which are later sent to fields on another page that is printed. I need to
limit the amount users can type into the fields, as opposed to the scrolling
that occurs now (even with a rectangular field instead of a scrolling one),
so that the answers will fit into the printed fields. I can't for the life
of me figure out how to do this.

Thanks in advance!
