Subject:      CAN ANYONE TELL ME THE CORRECT WAY TO DO IT?
Content-Type: text/plain; charset=gb2312

Dear SPSS-Lers,
　　　　　　　 I wonder if someone could find a solution for me about
the following command. I use an if command to find the cases I want and
then change the values of two variables. The if statement works fine
now, but I can't change the values of the two variables at the same
time. If I change one variable, it is ok. I do need to change the values
of the two variables at the same time though. Can anyone on the list
suggest a solution? Thank you in advance for your help.
