Re: first and last observations using proc sql. Since SQL is a column based language, doing calculations according to row numbers is not SQL's cup of tea. Maybe you can do some complicated query using the unsupported monotonic function. But, this is so much easier done with data step.You must already have a variable named COUNT in the input dataset. So each time the SET statement runs the value from the input dataset overwrites the value from the previous observation. To get your example then COUNT is probably 1 for every observation. So that when you increment when ACTIVITY changes it goes to 2.

The best thing you did is accurately count the number of elements in your array. I'm going to sketch out valid code for what I think you are trying to do here. data test33; set perso.test; by epci; array sexage {101} sexage000 - sexage100; array sex {101} SEXE1_AGED100000-SEXE1_AGED100100; if first.epci then do i=1 to 101; sexage{i} = 0; end ...First, in order to use FIRST.var and/or LAST.var, the SET or MERGE statement must be followed by a BY statement. To use a BY statement, the dataset(s) must be sorted by the key variables identified. The BY statement will automatically create the SAS variables FIRST. and LAST. for each BY variable. If the first

Sad to read this. Luckily, this forum is full of nice people who spend a lot of their free time helping other members with their SAS (and statistics) questions.

The first two functions that actually remove blanks in SAS are the TRIM-function and the TRIMN-function. Both functions remove trailing blanks. However, they differ in how they deal with strings of multiple blanks. If a string consists of only blanks, the TRIM-function returns one blank, while the TRIMN-function returns zero blank characters.line @1 "*your notes here.
