MERGE.LIST Sorts automatically, The UNION does the DEDUPING
The 1 union 1 - says to union of list#1 with list#1 (itself) Otherwise: MERGE.LIST # ACTION # TO # Where ACTION = (UNION, INTERSECT or DIFF) And the TO # will save the results to that list# (if it's not specified, the default list #0 is used) George -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Chris Austin Sent: Thursday, May 17, 2012 5:00 PM To: u2-users@listserver.u2ug.org Subject: Re: [U2] SAVING UNIQUE ( multivalued) That works beautifully George, thanks for the tip! I've never used the MERGE.LIST command before, I assume the line you have > 0005: MERGE.LIST 1 UNION 1 basically take the list #1 and shakes out the unique values?
