How to identify previous month full name

jayakumarmm — Fri, 02 Sep 2016 14:01:45 GMT

I want to identify previous month full name .i.e. If current month is September then I want to retrieve August. Currently I am going with the below approach but this will fail for the month January. Please assist

month = month(input("&sysdate9",date9.));
lastmonth = int(month) - 1;
put(lastmonth,nlstrmon.);

You can use monname format:

month_name=PUT(date,monname.);

But be aware that this takes a date value as input.

format prev_month $20.;
Prev_month = put((INTNX('month', today(), -1, 'B')),monname.);

Since you have nearly working code, you could tweak it simply:

if month = 1 then lastmonth = 12;

else lastmonth = month - 1;

If you wanted to get into the depths of how SAS works with dates, you could modify your first statement:

lastmonth = month( intnx('month', "&sysdate9"d, -1));

As before, that gives you the month number which still has be to converted to the name.
