Subtract two columns and output difference to a new dataset

[JayCompany]

Hi,

  I have one dataset with 2 columns. I would like to subtract the two columns and output this difference to a new SAS dataset.  How would I go about doing this?

Original Table:

ID, A2017, B2018 

Desired Table:

B2018 - A2017

It's a little difficult knowing where to begin here.  Let's start with assessing what you already have and what you already know.

When you say you have a data set, is it already a SAS data set?

Do you know how to create a new SAS data set?

Do you know how to bring in data from an existing SAS data set?

Do you know how to create a new variable?

Do you know how to assign that new variable the outcome of a subtraction?

The solution will look incredibly simple in retrospect.  I'm just trying to determine how much of it you already understand, so the solution can focus on the rest of the question.

why didn't you try the most basic? Not trying to find fault, but these kind of questions may not be appreciated by most solution contributors.

data your_wanted_output;

set your_given_input;

new_column_c = column_b - column_a;

keep new_column_c ;

run;
