st: ICE with if statement

Hi all,
I am trying to multiply impute data per survey using ICE. However, I do not understand how the IF statement should be used to do this. When I use the following command, test1.dta still contains all surveys:

ice x1 x2 x3 using "G:\test1.dta" if survey==1, m(5)

Subsequently, I run:

ice x1 x2 x3 using "G:\test2.dta" if survey==2, m(5)

which results in test2.dta containing all surveys too.

As I understand it, there is no BY statement as in SAS PROC MI.
Can anyone tell me how to run imputations per survey?
Thanks in advance,
Stijn
