Jul 7, 2011 · As I understand what you want, you simply want the first and last records for a given ID on any date. If so, then you only need: data get_first_and_last; set master_table; by ID Date; if first.date or last.Date then output; run; Of course, if you only want the last record on a date then replace the if with: Your code only removes the first five and last five observation of the whole dataset which is over 3000 observations. What I want is to remove first five and last five observation for each bridge which has 25 observation each. The dataset of 120 bridges makes the 3000 observations. I only want to retain the middle 15 observation for each bridge.

Be precise in numbers: number of observations, number of variables, observation size. Also post what you expect as a result.SUBSTR() function only works with the character variable. In order to extract last N digits you need to first convert numeric variable into char variable using PUT() function before passing it to substr function. Here is the classic example of how to extract last 4 digits from a numeric variable in SAS.If you use a by statement along with a set statement in a data step then SAS creates two automatic variables, FIRST.variable and LAST.variable, where variable is the name of the by variable. FIRST.variable has a value 1 for the first observation in the by group and 0 for all other observations in the by group.Example 13.13. The following program tells SAS to process the sales data set by Store and Dept, so we can get a behind-the-scenes look at how we can find the first and last observations of two subgroups: LIBNAME stat481 'C:\yourdrivename\Stat481WC\01sasdata\sasndata'; PROC SORT data = stat481.sales …Major Mike Sadler, the last surviving member of the famous wartime squad known as L Detachment SAS, has died at the age of 103.The legendary squad nicknamed themselves 'The Originals', with Mike ...Hi: FIRST.byvar and LAST.byvar are automatic variables that exist for the duration of the DATA step program, but they can be used in the program. Since they are never output to the final dataset, you might consider them temporary. I prefer to think of them as automatic, like _N_ and _ERROR_, which are also available for the duration of the program but not output.As was shown, MONOTONIC () is unreliable when used in conjunction with a HAVING clause.

Re: Changing the Column positions in SAS. the easiest way to change the column order, is to create it in the correct order first, then you won't have to change the order afterwards. Advice you have received on setting column order, should be applied when you create the dataset/table.Here is a solution that avoids number to character conversion and back again, and also deals with fractional and negative values. int (abs (num)/10** (log10 (abs (num))-3)) It works by dividing the number by the requisite power of 10 (including negative power) and truncating the decimal portion.

You can process observations conditionally by using the subsetting IF or IF-THEN statements, or the SELECT statement, with the temporary variables FIRST. variable and LAST. variable (set up during BY-group processing). For example, you can use them to perform calculations for each BY group and to write an observation when the first or the last observation of a BY group has been read into the ...The best thing you did is accurately count the number of elements in your array.
