* First we need to calculate a grossing-up weight .
* since it was not on this version of the file.
* It is not crucial for this to be accurate when (as here) .
* the sampling fraction is quite small.

compute gross_wt=ind_wt*4000000/28685.
execute.

* Now we need to set up the plan file which can be done. 
* most easily interactively (see the mini guide).
* This syntax was generated by pasting from the menu .
* You will need to change the name of the plan file to its file name on your machine.

* Analysis Preparation Wizard.
