Here is my dream:

create cursor mycursor (year i,saled i)
insert into mycursor values (1999,1000)
insert into mycursor values (2000,1200)
insert into mycursor values (2001,1800)
insert into mycursor values (2002,900)
insert into mycursor values (2003,2700)
insert into mycursor values (2004,5400)
insert into mycursor values (2005,540)
alter table mycursor add column growth n(5,2)


SELECT MyCursor
m.lnOldYear=MyCursor.Saled
SCAN
    mychange=MyCursor.Saled- m.lnOldYear
    ipercent=100*mychange/m.lnOldYear
    REPLACE MyCursor.growth WITH ipercent
    m.lnOldYear = MyCursor.Saled
