You probably need the 'ifempty' option of 'strliteral' for that. PS Be careful to look at 'pipe help literal' (although for syntactical reasons you can not use it there). The strliteral alias is missing from the helplib so you get the (incomplete) CMS HELP version... Rob -- Rob van der Heij Velocity Software GmbH http://velocitysoftware.com/
