I have understood my error. I thought that f1: :a1 was meaning "let use a1 as pointer constantly" and not "point to the content of a1 and then do not use a1 anymore". For the rest of you message I admit I have marked it "for further study". I am still a beginner in Rebol and you I need time to comprehend it. Giuseppe Chillemi
