If the argument is blank, KSTRIP returns a string with a length of zero. Assigning the results of KSTRIP to a variable does not affect the length of the receiving variable. If the value that is trimmed is shorter than the length of the receiving variable ...Hi, Blanks at the end of a string are preserved by default. In fact, if you assign a value to a character variable and the value is shorter then the length of the variable, SAS will pad the value with blanks. In below example, STRING1 and STRING2 have the same value (5 a's followed by 5 blanks).Details. A SAS datetime value is the number of seconds between January 1, 1960 and the hour, minute, and seconds within a specific date. The DATEPART function determines the date portion of the SAS datetime value and returns the date as a SAS date value, which is the number of days from January 1, 1960.The TRIM macro and the QTRIM macro both trim trailing blanks. If the argument contains a special character or mnemonic operator, listed below, use %QTRIM. QTRIM produces a result with the following special characters and mnemonic operators masked so the macro processor interprets them as text instead of as elements of the macro language:I want to remove outliers using median +/- 1.5 IQR (Qrange in SAS). The proc univariate can generate median and Qrange, but how do I use these values in another proc or data step? Another way is to use proc sql, but it seems proc sql summary function does not have qrange .

As you can see from the first SQL clause, the function itself does not necessarily trim to $200. It returns the full result when used with proc SQL when a length is assigned. What does the trimming is calling the function within a case statement. The length defined after the case test is not passed on to the function.Need to seperate the comma delimited full name to last name and first name.

Otherwise you may experience truncation of your values. Note that CATX may tell that you need a longer variable with a message.Details. The RENAME statement allows you to change the names of one or more variables, variables in a list, or a combination of variables and variable lists.

In a 2010 paper I described how to use SAS/IML software to trim data. Trimming is the act of truncating the upper and lower tails of the empirical distribution of the data. Winsorizing is slightly more complicated, especially if the data contain missing values or repeated values.

The easiest way to remove the first character from a string in SAS is to use the SUBSTR function.. You can use the following basic syntax to do so: data new_data; set original_data; string_var = substr (string_var, 2); run; . This syntax extracts the substring starting from the second character to the end of the string, which has the effect of removing the first character from the string.

The Basics. TRIM copies a character argument, removes trailing blanks, and returns the trimmed argument as a result. If the argument is blank, TRIM returns one blank. TRIM is useful for concatenating because concatenation does not remove trailing blanks.The CATS function returns a value to a variable, or returns a value in a temporary buffer.

If variables are padded with trailing blanks, check the lengths of the variables and use the TRIM function to trim trailing blanks from values before concatenating them. See SAS Language Reference: Dictionary for descriptions and examples of additional character functions.SUBSTRN would not be idiomatic in most cases; SUBSTRN is basically the same thing as SUBSTR except that it can return a null string, while SUBSTR cannot (in most cases in SAS, null string is impossible, so a few functions were later added TRIMN and SUBSTRN that can). Normally you wouldn't use that version unless you did need the possibility of a null string.I have a variable in the form of yymmdd, and I want to extract yymm from it without changing the date format.

If by "top and bottom 1%" you mean by data volume rather than data distribution, then just derive the first and last obs for that percentage. I'd think this would perform much faster than PROC RANK for large datasets. Something like this (code untested, so just use it as a guide): data _null_;, CATT(item1, item2 <, item3, item4, …, item n>). CATS(item1, item2 <, item3, item4, …, item n>).
