Turn validation on for the field and use a calculation:

Length( Your_Field ) = 22

You can also make this strict, which means the user can't override this, and you can show a custom dialog box when the validation fails.

Filemaker 5.5 has added a validation entry that permits you to set the max characters without a calculation. I do not think it cares if you have LESS than the max, though, and Chuck's solution will work irrespective of version.
