You've chosen a combination where PAD will never do anything: column ranges defined in words, and PAD BLANK. Since a word can never end in a blank, padding with blanks will never change what does or doesn't match. Suppose you had words with an unpredictable number of dots stuck on the end. Then |LOOKUP PAD . W1| would match up, say, "word." with "word.." or "word" with no dot. I don't know whether the guts of LOOKUP would make this easy or impossible, but it sure would be nice to be able to say PAD ANYOF and specify a list of characters that match the end of the other key (and maybe a shorthand ANY for ANYOF 00-FF). Even nicer if we could also PAD LEFT to handle BC's domain-name problem without having to reverse the records. ¬R Blather, Rinse, Repeat. http://users.bestweb.net/~notr/telecom.html
