----boundary-LibPST-iamunique-1900413059_-_- Content-type: text/plain I want to thank Alexander Iljin and Wojtek Skulski for their help in explaining how to use type guards in working with extended records. I had not understood the explanations in the BlackBox documentation, nor in the Hanspeter Mössenböck book, but they made it simple. THANKS!!!
