sas programming

[hamilton1]

se an array and iterative processing to clean the survey data (located above this HW assignment).  Call your newly cleaned data set "cleansurvey".  Begin by identifying all of the dirty data (please highlight these in your SAS proc freq results.)  The Arrays lesson shows you how to change the 99s to blanks.  You also need to correct all typos.  Run proc freq again on your cleaned data to show that you were successful.

What you tried so far?

I am not sure what to do

I suggest you start by writing a data step to change the 99s to blanks. Use the results of the proc freq to see what else you need to change.

Your instructor was kind enough to point you to the relevant resource: The Arrays lesson shows you how to change the 99s to blanks.
