Next: SAS variable format won't change?
From: PC on 29 Mar 2010 11:29
I know for numeric values, you can specify condition like, between 100
and 1000; in SQL , you can use character , such as between '120.0' and
'120.9';
Is there any way to do that in SAS which will be very useful?
I am asking this, because for ICD9 code, some diseases are defined as
560.3-560.9, there are also some minor codes, such as 560.41 etc. I
can not list all of them using icd9 in (1,2....)

Thanks
