Handling missing values at once?
Handling missing values at once?

Hello,

I was wondering is there any code to put all of my missing value of -1 to 0 at once.

I have variables

V1 to V20, and they all include -1 as a missing value.

I've tried

recode V1-V20 -1=.

But does not work.

Any suggestions?
