Hello!
I am using SAS ver9.3 to sort observations. They are as follows:
NT1
NT2
T1
T2
T3
I would like to sort them as:
T1
T2
T3
NT1
NT2
A simple DECENDING statement does not work, and give me T3, T2, T1, NT2, NT1. Is there a proper way to sort this? Thank you in advance. I am new at SAS programming so apologies if there is a simple solution I am not realizing.

Well, there's not really a simple solution. SAS isn't built to sort in an order that is neither ascending nor descending. You would need to create an extra variable based on your old variable:
if oldvar =: 'T' then sort_order=1;
else sort_order=2;
Then use that as part of your sorting sequence:
proc sort data=have;
by sort_order oldvar;
run;
