temporary variables: FIRST.Age and LAST.Age. SAS reads ahead by one observation as it passes through the data and sets the automatic variable values to 1 when the first or last values in a group are processed and 0 otherwise. The FIRST.variable and LAST.variable values indicate whether an observation is: • the first in a BY groupIn that case, SAS would not set any flags or automatic variables other than _N_, _ERROR_, etc. However, if you WANT to use FIRST.byvar and LAST.byvar processing then you have to "turn them on" with a BY statement inside your DATA step program. So the 2 BY statements in your code are really independent of each other.If you want to do so with PROC SQL, this has nothing to do with first./last. logic, which is a SAS Data Step concept. proc sql; create table want as. select * from sam. group by name. having value=min(value); quit; Result: name item value. naari battary 14. nehemiah ball 20.The following code shows how to extract the first 4 characters from the team variable: /*create new dataset*/ data new_data; set original_data; first_four = substr (team, 1, 4); run; /*view new dataset*/ proc print data =new_data; Notice that the first_four variable contains the first four characters of the team variable.Aug 24, 2014 · I need the output of purge='n' and record having highest date with purge='p' . data purged; input acc purge$ date ; datalines; 111 p 234 234 n 1333 1111 p 2345 2234 n 1333 1121 p 2334 2334 n 3233 ; run; proc sort data=purged; by purge date ; run; data purgedorder; set purged; by purge da...

For all the next observations of the same date, the condition 'if first.date' is false so SAS applies the 'else' statement, which results in the accumulation of seq_id's previous value + 1 -> so ...

Example 1: Print Entire Dataset Observations. The fundamental of this procedure is to print observations from the SAS dataset. It can be done simply by invoking the PRINT procedure by passing the dataset name. Here is a simple example to print all the observations from work.my_cars.

Hi, I have a dataset in which Obs can become either "1" or "0". For every observation where Obs is "0", it needs to be determined the time when Obs started to be "0" (Time_first), the next time it becomes "1" (Time_last), and the time of …The sample code on the Full Code tab takes a SAS date variable and finds the first business day of that month. It uses the INTNX function to advance to the first day of the month. Then it uses the WEEKDAY function to determine the day of the week. If the first day is a Saturday or Sunday, then it advances the FIRST variable by 2 or 1, respectively.Join us for SAS Innovate April 16-19 at the Aria in Las Vegas.
