Hello Alexander Thanks for your response. As often, one answer leads to more questions. Sorry for that ;-)

Do I understand correctly that I should use the condition 'additional parameter' to check this user parameter? Also, does the user parameter stay with the message indefinitely across invocations of the Bat! or is it only there during the time the filter is active? ASK> PS: you have two sig delimiters in your message, one would do better :) I fully subscribe to the less-is-more principle. In this case I should have done less pasting and/or more cutting!
