I like it! Once improvement: if the 2nd select fails, you should clear select list #1. Something like this:
CMD = "" CMD<-1> = "PA" CMD<-1> = "SELECT REGISTRATION WITH EID = '1' SAVING UNIQUE PID TO 1" CMD<-1> = "IF @SYSTEM.RETURN.CODE < 1 THEN GO THE.END" CMD<-1> = "SELECT PEOPLE TO 2" CMD<-1> = "IF @SYSTEM.RETURN.CODE < 1 THEN GO JUMP1" CMD<-1> = "MERGE.LIST 2 DIFF 1" CMD<-1> = "GO THE.END" CMD<-1> = "JUMP1:" CMD<-1> = "CLEARSELECT 1" CMD<-1> = "THE.END:" EXECUTE CMD Even so, very cool!
