Karen:
Are you trying to subset a dataset that contains a SAS date variable
(such as the DATEPART() of a time stamp)? If so, you should compare the
value of the date variable (say, date) to the value of the DATE()
function in a subsetting IF statement:
data t1;
  set t0;
    IF date = DATE() -1;
run;

Hello, All.

I run a job everyday, and I only want obs. from the previous day.  I do
not want to have to change the day every day, so I tried this:
CODE:
  Today = Date();
  Yesterday = Today - 1;
  If Yesterday lt Today;

  put @30 today  @40  yesterday ;
           17714        17713

Why didn't the above code select obs for June 30th.?  There are obs. for
that day.

Thanks In Advance
