[RBASE-L] - Display Feedback on Data with the IFF function

[Dr. Fritz Luettgens]

Hi,

year(col1)      turnover(col2)          info(col3)
2011            3
2012            6                       +
2013            5                       -
2014            7                       +

I want to add to the info column  "+" or  "-"
with the UPDATE command using the
 IFF function (IFF('.v1<.v2','+','-'))
but cannot get it working because I think I
need the year as reference.
Is there a different function I can use ?
Thank´s
fritz
