To specify a different length, include the desired length after the $ for character arrays and after the brackets for numeric arrays, as shown in these statements: array name[3] $10 first last middle;The Right Way to Obtain Duplicates in SAS. To obtain ALL duplicates of a data set, you can take advantage of first.variable and last.variable . Here is the code to do it with the above example data set of test; you will get both the single observations and the duplicate observations.The YEAR w. format is similar to the DTYEAR w. format in that they both write date values. The difference is that YEAR w. expects a SAS date value as input, and DTYEAR w. expects a datetime value. Examples. The example table uses the input value of 16601, which is the SAS date value that corresponds to June 14, 2005. SAS Statement.Example: if first.variable_name then do; ratevalue = 999; factor = 100.00; end; the first.variable is the 6th variable in the groupby. The first column in the group has a date value of '3-20-2017' hardcoded. So there is only 1 group with the fist column comprising of all 200K observations. Question is when I execute the above piece of code I am ...

What is FIRST. & LAST. ? The SET and BY statements in a data step tell SAS to process the data by grouping observations together. Whenever we use BY …Launch the SAS program, and edit the LIBNAME statement so that it reflects the location in which you saved the background data set. Then, run the SAS program, and review the output from the PRINT procedure. Compare the output to the output of that from the previous example to convince yourself that the temporary data set back1 indeed contains fourteen observations — observations 7, 8 ...data temp1; set temp; by i t; if first.i or lag1(first.i) or lag2(first.i); run; Can one pick up every last, second last, and third last observations in a similar way?

A more important question would be why the "data" is like that in the first place. It looks a bit like your reading in a produced report - not a recommended approach for multiple reasons (populations, calculations, assumptions etc.). Get the real "data" and use that.
