As an addition to the previous post today, I would like to share another interesting information with you.
Starting with NAV2013 it is possible to leave the Length-field of a text-variable empty. This enables you to fill in as many characters as you wish.
My thanks go to Navigateintosuccess-blog for sharing this information.
