It's not clear why this task of finding a first name is being done via macro functions rather than a SAS data step and data step functions. Your data will be in a SAS data set, use the proper tool, use SAS data steps and data step functions.--While you may have obscure problems with names like Vincent Van Gogh, your basic idea for first and last name are correct. You can check whether there are 3 names, and only assign the middle name if there is one. The DATA step syntax is easy: if countw (fullname) > 2 then second = scan (fullname, 2, ' '); The SQL syntax is harder, and just a ...Re: substract/divide each row from first row. No need for a multiple TABLE if you just want to assign values to multiple VARIABLES. Below I will show a way you could keep your "matrix" shape, but it looks like you should just restructure your so that instead of multiple variables you have multiple observations.One reason not to place names in a single field, typical reporting on names often is done on alphabetical by last name then first name. Second names with embedded spaces get hard to distinguish which is first or last programmatically when needed. If you separate them at entry then there is never a question.

When the LAG function is compiled, SAS allocates memory in a queue to hold the values of the variable that is listed in the LAG function. For example, if the variable in function LAG100 (x) is numeric with a length of 8 bytes, then the memory that is needed is 8 times 100, or 800 bytes. Therefore, the memory limit for the LAG function is based ...

Enumeration in SAS - within a group and by group (concept of first.variable and last.variable) · Comments14.Re: first.id and last.id. Whenever you are using the BY statement the source data need to be sorted in the same way as specified in the BY statement. Exception: when the data is stored in SPDE, SPDS or an external RDBMS the sorcerer engine sorts the data on the fly based on your BY statement.

The values of both FIRST. and LAST. variables in SAS are either 1 or 0. FIRST. variable = 1, when an observation is the first observation in a BY group. FIRST. variable = 0, when an observation is not the first observation in a BY group. LAST. variable = 1, when an observation is the last observation in a BY group.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 by statement that we used above not only caused SAS to process the data in the groups defined by the variable (famid) given on the by statement, it also caused SAS to create two temporary variables: first.famid and last.famid. Temporary variables are variables that you can use during a data step but do not appear in the new data set.Breaking down line-by-line: data df1; set df; Create a new data set called df1, and read the values from df into it row-by-row.. by id; When reading df row-by-row, read it in ordered by the variable id.. retain flag_final; When reading a new row, initialize flag_final as the last value it was given.. if first.id then do;would be or even what the last variable in the list would be when the code was written. In the above example for &pggrp = 016_017 the string FIRST.&&KEY&KEYCNT resolves to FIRST.OCC1. Since there are three variables in the BY statement, &KEYCNT is 3, and &KEY3 is OCC1.

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.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.then First.date refers to the first player's record within the date. Also your Days calculation is probably incorrect as you are getting some days, the first days value for each team (except the first team) reflects the days between the last game of the previous team and the first of the current team. days=game_date-lag(game_date);Hi, I am doing this in a length way so wondering is there is anything simpler - How do I keep only first row and the last row in a table? I need to assign a macro to the date value in the first row and another macro to the date value in last row of the Date variable. Example: Name Response Date A 1...Re: First dot and last dot conversion into proc sql. There is no such thing. SQL does not guarantee the order in which it selects observation, so the "last" observation is unreliable. It could change from run to run. There is an unsupported, unguaranteed "monotonic" feature of SQL if you want to go that route.While Andreas already answered your question, I thought you might find it equally useful to know that the reason that you don't have to include Total_Amount_Last_Learning in a retain statement is because it is automatically retained because you used in the statement TOTAL_AMOUNT_LAST_EARNING + AMOUNT_LAST_EARNING ; . The variable on the left in such sum statements are automatically retained.6. I have recently migrated to Python as my primary tool for analysis and I am looking to be able to replicate the first. & last. functionality found in SAS. The SAS code would be as follows; data data.out; set data.in; if first.ID then flag = 1; if last.ID then flag = 1; run; The output would be as follows;The DO statement, the simplest form of DO-group processing, designates a group of statements to be executed as a unit, usually as a part of IF-THEN/ELSE statements.
