The SDA site provides an option to run the RECODE and COMPUTE programs on some of the most commonly used datasets.

These programs allow you to create new variables derived from existing variables in each dataset. The new variables are placed into a public work area, which is available to all users of the SDA Website.

Note the following:

• Please delete new variables you created but no longer want to use.

• Anyone can overwrite or delete a variable in the public work area. We urge users to be considerate of the work of others, but we cannot enforce such behavior.

• The new variables will not remain in the public work area indefinitely. When the work area gets too full, we will have to delete some of the variables, beginning with the oldest ones.

• If you want a more permanent and private work area, we can set one up for you, but there will be a fee for doing so. Click here for more information on this service.
