Mike Sadler, who has died aged 103, was a former MI6 officer and an honorary member of "the Originals", as men of L Detachment of the early SAS are known. He was believed to be the last survivor of the Long Range Desert Group or LRDG, without which the fledgling SAS might not have thrived. He also has a piece of the Antarctic named after him.
Note that in some cases, I just need the unique instances of the variable (such as with On_Off) but in other cases I need every instance (such as with Group). I have been trying first./last. processing with by statements, but I can only get that to work with one variable at a time. Is there a way to do this for N variables within the same data ...I have a dataset that has variables ID, Date, and Value. For each ID that has more than one Value, I want to output the earliest observation into a new column 'First', and the latest observation into a new column 'Last'. For IDs that only have one Value, I want the observation to be ignored. The final aim is to do a scatter plot of 'First' vs ...

A temporary flag is added to the data, called first.<variable> and last.<variable> for each variable in the by group, this flag can then be used to determine if the record is the first or last occurence within the by group. There are many guidance documents out there about this:You can extract the last 2 characters of the text strings, with the following 3 steps: 1. Determine the length of the string with the LENGTH function. 2. Specify the starting position to extract the last N characters. You do so by subtracting the N-1 characters from the length of the original string. 3.I want to output the last value of a variable pr. sub-group to a SAS dataset, preferably in just a few steps.

FIRST-dot and LAST-dot processing is a topic that deserves its own tutorial, but you can learn more from this article by @Rick_SAS. Tip: FIRST-dot/LAST-dot processing is a great use case for the DATA step debugger (in SAS Enterprise Guide or SAS Studio with SAS Viya). You can see exactly how it works with your DATA step logic.
At the very first observation of each group (identified by the internal variable first.date, which takes the value 1 in this case), seq_id is set to 1. 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 ...Removing the first observation of duplicates.
