Actually, I think I've just remembered part of it, but not the rest. Appends an empty string:
REC = "A" REC<-1> = "" Doesn't append an empty string: REC = "" REC<-1> = "" Sets REC<2> to an empty string: REC = "A" REC<2,-1> = "" Doesn't append an empty string: REC = "" REC<1,-1> = "" I think my mind hasn't returned from vacation yet... Interesting that it changed in UniVerse though, Kate. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Kate Stanton Sent: Monday, May 03, 2010 3:53 PM To: U2 Users List Subject: Re: [U2] <-1> and Null values Hi Dan, You are not the crazy one. It changed some years ago (UniVerse anyway) - we found out the hard way. That and the user number not being the user number for phantom (ie client) users have caused a great deal of heartache for us. Scary thing is what else might change! We avoid use of NOT() when data might be alpha, in case that changes to give runtime error.
