Which operator support if then else? I would like to assign a new or replace the value of an attribute based on the value of another attribute:

Example:

If ACTIVITY != "Tumble"
    DIFF= 0
else
    DIFF = BARODIFF

ACTIVITY, DIFF and BARODIFF are attributes of my data set.

Thanks!

    hi..I would do this in "Generate Attributes".  You can then go to Edit List and under attribute name, name your new attribute DIFF.  Under function expressions, do something like this:

    if(ACTIVITY!="Tumble",0,"BARODIFF")

    or something like that.
