Re: st: Question using macro in loop

[Tak-wai Chau <tchau@troi.cc.rochester.edu>]

First forget about the specific example I used before.

Now we have variables V1, V2,..., V10.
We have another variable W contains integer values between 1 and 10 
inclusively.
We also have another variable Y contain numerical values.
I want to set Vi=Y if W==i for that observation and let other Vs 
unchanged for that observations.

So what can I do in this case?

Hope this is clearer now.

Thanks a lot!
