The technique you are using is better for test if a string is a number, so strings like 1e4 would be read correctly. If your numbers could include commas or dollar sign use COMMA informat. If you are trying to see if string is a SAS name NVALID function. [pre] data _null_; input string $16.; x = anydigit (string);run; options nocenter nodate nonumber; proc print data=capture_val; title 'Values of FIRST. and LAST. variables are 0 or 1'; run; produces this output from the PROC PRINT. You can see that the "hold" values for FIRST.SASID, LAST.SASID, FIRST.CUL and LAST.CUL are only 0 or 1.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 next observation (Time_next). The best solution I found ...Special Functions and CALL Routines: Matrix CALL Routines. Special Functions and CALL Routines: C Helper Functions and CALL Routines.

Example 1: Finding the First and Last Words in a String. The following example scans a string for the first and last words. Note the following: A negative count instructs the SCAN function to scan from right to left. Leading and trailing delimiters are ignored because the M modifier is not used.

Then using first. and last. variables and 2 cumulative (summarized) variables, you can generate this #1 report using the data set created in the DATA step program. I also included 2 separate steps for PROC REPORT and PROC TABULATE that generate the numbers you want without using a DATA step program:PROC REPORT honors the first of these centering specifications that it finds: the CENTER or NOCENTER option in the PROC REPORT statement or the CENTER toggle in the ROPTIONS window. the CENTER or NOCENTER option stored in the report definition that is loaded with REPORT= in the PROC REPORT statement.

As you can see the have data set has multiple cal columns. Since this is transposed data that i have it can have any number of val columns. My requirement is, I need the last column value(if its not null) as the first column value in the want data set. Some id can have all the val columns with data, some can have only few val columns with data.proc sort data =work.revenue_by_group. out=work.revenue_by_group_srt; by group date ; run; STEP 2: Calculate the Cumulative Sum by Group. Now that we have ordered the dataset by Group, we can calculate the cumulative sum. Like the previous example, we use the RETAIN statement and IF statement.BYステートメントとFIRST.変数を使用して、連番を付加することができます。.

The first week of the year, Week , and the last week of the year, Week or , can include days in another Gregorian calendar year. If the descriptor is 'W', ...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 …Re: READ only first and last obs. The first SET statement reads the first observation from the source table as you're used to it. The OUTPUT statement then writes this row to the target table. The second SET statement then uses direct access via keyword point=_nobs_. This reads the observation number stored in _nobs_ from the source table - and ...You cannot use variables that are created within the DATA step (for example, FIRST. variable, LAST. variable, _N_, or variables that are created in assignment statements) in a WHERE expression because the WHERE statement is executed before the SAS System brings observations into the DATA or PROC step. When WHERE expressions contain comparisons ...

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 ...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. Richard.In one case, Van Arsdale (words 2 and 3) are the last name; in the other case, Billy Bob (words 1 and 2) is the first name. Now, in your simple John Smith or Jane Smith cases, removing Jr Sr IV III is easy. The problem is much harder in general, and there's probably no solution that will work on every name in the list.In 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.I have data set like below... data stansys; infile datalines; input id name&$24. sal; datalines; 101 Richard Rose 5000 102 Yao Chen Hoo 6000 103 Asha Garg Bette Long 7000 104 Jason Blue 9000 105 Susan Robert Stewart 8000 ; run; Through this dataset i want output dataset with seperating as First name and Middle name and last name...Re: Remove Duplicates First. and Last.
