Code replacing the last column.

[StefB]

Hi all,

I am VERY new to SAS and my question may come off as ignorant, but is there a reason why every time I run my code it keeps replacing the last column.  For instance, I needed to do the Year of Birth and once I ran it, it replaced the column of my last code I ran, but none of my raw data is replaced its just the code I write for.  I hope this makes sense.  Thank you!

Post the code you ran and an example (in the form of a data step) of your data.

As @art297 mentioned, we're missing a lot of the specifics here.  Here's the general answer.

You might be looking at expected behavior of the software.  For example, consider these types of programs:

data new;

set old;

** statements to make changes to the data;

run;

data new;

infile 'some source of text data';

input some list of variables;

** statements to make changes to the data;

run;

In both cases, the changes apply to the data set being created only (named NEW in both examples).  None of the changes are expected to appear in the incoming source of data.

What does your data and code look like?
