The %QUOTE and %NRQUOTE functions mask a character string or resolved value of a text expression during execution of a macro or macro language statement. They mask the following special characters and mnemonic operators: + - * / < > = ¬ ^ ~ ; , # blank. AND OR NOT EQ NE LE LT GE GT IN.In my previous post, we solved the task of removing specified leading characters from SAS strings. In this post, we tackle the complementary task of removing trailing characters.. While removing trailing blanks is well covered in SAS by the TRIM() and TRIMN() functions, removing non-blank trailing characters remains a bit of a mystery that can pop up during text string processing.SAS Index Function. The SAS INDEX function searches the source string, from left to right, to find the first occurrence of the string specified in the excerpt, and returns the position in the source of the string's first character. If the string is not found in the source, INDEX returns a value of 0. If there are multiple occurrences of the ...So you cannot use SUBSTR (CODE,9,2) because 2 is an impossible length when starting on the last character. One way to avoid having to specify the length is to let SAS do the truncation by defining the target variables as length $2. data f12; set f12; array type $2 type1-type5; do i=1 to 5 while (2*i-1 <= length (code));The LENGTH statement forces SAS to add 7 trailing blanks to pad string to be of length 10, so the value of POS1 is 4, the position of the first trailing blank. One way to avoid the trailing blank problem is to remove the trailing blanks before using the verify function. The TRIM function does this for us. We use TRIM first for POS2, so now with ...The expression also uses the TRIM function to trim trailing blanks from the character value. This way an exact match is found between the character string in the input data and the value of the array element. The following output that PROC PRINT generates shows the resulting data set OFFICE2. Data Set Office2The CATX function returns a value to a variable, or returns a value in a temporary buffer. The value that is returned from the CATX function has the following length: up to 200 characters in WHERE clauses and in PROC SQL. up to 32767 characters in the DATA step except in WHERE clauses. up to 65534 characters when CATX is called from the macro ...While SAS 9.4 BASE TRIM() function capabilities are quite limited - it removes just trailing blanks from a character string, the FedSQL TRIM() function is way much more powerful. This triple-action function can remove not just trailing blanks, but also leading blanks, as well as both, leading and trailing blanks. ...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.Looks like you already have your answer, but I'd like to offer more features to support what you seem to seek. 1 The select into: clause provides a feature NOTRIM to maintain lead/trailing blanks - if you need those.If you use an undeclared variable, it will be assigned a default length of 8 when the SUBSTR function is compiled. When you use the SUBSTR function on the left side of an assignment statement, SAS replaces the value of variable with the expression on the right side. SUBSTR replaces length characters starting at the character that you specify in ...Sep 2, 2021 · While removing trailing blanks is well covered in SAS by the TRIM () and TRIMN () functions, removing non-blank trailing characters remains a bit of a mystery that can pop up during text string processing.

In a DATA step, if the SUBSTR (right of =) function returns a value to a variable that has not previously been assigned a length, then that variable is given the length of the first argument. The SUBSTR function returns a portion of an expression that you specify in string. The portion begins with the character that you specify by ...1. length is a declarative statement and introduces a variable to the Program Data Vector (PDV) with the specific length you specify. When an undeclared variable is used in a formula SAS will assign it a default length depending on the formula or usage context. Character variables in SAS have a fixed length and are padded with spaces on the right.May 5, 2020 · Re: Leading blank in strings.

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.Details. The TRIM function 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.(Both might benefit from using the TRIM function in case your incoming string has trailing blanks that you want to get rid of.) The first approach fails because the program assigns SAMPLKEY a length based on the first mention.SAS® 9.4 Macro Language: Reference, Fifth Edition documentation.sas.com. SAS® Help Center.

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. The new variable names are written to the output data set only. Use the old variable names in programming statements for the current DATA step. RENAME applies to all output data sets.The INT function returns the integer portion of the argument (truncates the decimal portion). If the argument's value is within 1E-12 of an integer, the function results in that integer. If the value of argument is positive, the INT function has the same result as the FLOOR function. If the value of argument is negative, the INT function has ...The Basics. In a DATA step, if the LEFT function returns a value to a variable that has not previously been assigned a length, then that variable is given the length of the argument. LEFT returns an argument with leading blanks moved to the end of the value. The argument's length does not change.The expression also uses the TRIM function to trim trailing blanks from the character value. This way an exact match is found between the character string in the input data and the value of the array element. The following output that PROC PRINT generates shows the resulting data set OFFICE2. Data Set Office2TRIM= values <(<TYPE= keyword > <ALPHA= >)> requests a table of trimmed means, where value specifies the number or the proportion of observations that PROC UNIVARIATE trims.

If the SAS code runs in SAS with a WLATIN1 session encoding, the characters will each be represented as one byte. However, if the same SAS code is run in UTF-8, the Euro character will require 3 bytes. Table 2 shows the hexadecimal representation for these characters in WLATIN1 and UTF-8.Before executing the DATA step, SAS looks through the code and sets up storage space for all the variables that it will be using. When it sees these statements, it needs to make a decision: First = scan (name, 1); FirstName = trim (First); It needs to decide how many characters to use to store First and FirstName.proc sql trim.

However, I observed that there is an extra space is appended with few of the variables in the output XML file and I want to remove the extra spaces as highlighted in yellow below. Since the values are coming from the dataset, I think I've apply trim ...By the time the macro executes, the string is already masked by a macro quoting function. Therefore, %STR and %NRSTR are useful for masking strings that are constants, such as sections of SAS code. In particular, %NRSTR is a good choice for masking strings that contain % and & signs. However, these functions are not so useful for masking ...Details.
