i have a column called annualreportdate
that column has observations such as dec2012, dec 2010, dec 2011, current
1.) how do i delete all the rows with current?
1.1) instead of deleting, how do i replace those with 2013?
2) i also want to remove all the dec from dec 2012, dec 2010....and so on.
plz help!
One way to remove creating a new data set:
data want;
set have;
if annualreportdate="current" then delete;/* have to assume the variable is character if the value is actually "current"*/
/* you also may have to address case if sometimes it is current, Current, or CURRENT, so better would be*/
if upcase(annualreportdate) = "CURRENT" then delete;
run;
To modify a value:
if upcase(annualreportdate) = "CURRENT" then <do something>;
could be
then annualreportdate='2013';
or
then annualreportdate=tranwrd(annualreportdate,'dec','');
