I have a dataset which looks like this.

data have;
infile datalines truncover;
input type $ quarter phase counter percent avg std;
datalines;
XX-A 202001 1 30 20 20 1
XX-A 202002 1 50 2 20 1
XX-A 202003 1 60 2 20 2
XX-A 202004 1 50 10 20 2
XX-B 202001 2 30 4 30 3
XX-B 202002 2 60 4 30 3
XX-B 202003 2 70 1 30 3
XX-B 202004 2 20 3 30 3

I want to create a new column named STATUS based on the following if/case statements:

If count is < (avg + std * 1) = 'green'

if count > (avg + std * 1) and < (avg +std * 2) = 'yellow'

if count > (avg + std * 2) and (avg + std * 3) = 'orange'
if count > (avg + std * 3) = 'red'

The first step is always determining in your own mind (i.e. not even SAS code at this point) valid rules that will create these colors. I have added in red modifications to what you typed to produce valid rules

 

counter <= (avg + std * 1) then 'green'

counter > (avg + std * 1) and <= (avg +std * 2) then 'yellow'

counter > (avg + std * 2) and <= (avg + std * 3) then 'orange'
counter > (avg + std * 3) then 'red'

 

From there, SAS code is relatively easy to produce.

 

data want;
    set have;
    length color $ 6;
    if counter <= (avg + std * 1) then color= 'green';
    else if counter > (avg + std * 1) and counter <= (avg +std * 2) then color='yellow';
    else if counter > (avg + std * 2) and counter <= (avg + std * 3) then color= 'orange';
    else if counter > (avg + std * 3) then color= 'red';
run;

There are some minor simplications you can make to the above, such as changing the next to last line to

else color='red';
