If you do not specify lengththe Substrn in sas function returns the substring that extends from the position that you specify to the end of the string. ABS Function. ADDR Function.

Returns a substring, allowing a result with a length of zero. If string is numeric, it is converted to a character value that uses the BEST Leading and trailing blanks are removed, and no message is sent to the SAS log. If you do not specify length , the SUBSTRN function returns the substring that extends from the position that you specify to the end of the string. If you do not want the first argument to be evaluated as a macro expression, use one of the macro-quoting functions in the first argument. About This Book. CDF Bernoulli Distribution.

Returns a substring, allowing a result with a length of zero. Date, Time, and Datetime Constants. Function Categories. Client Authentication Using an Authinfo File. Example Data Sets. SAS Visual Analytics. SAS Studio. CASL Reference. Required Arguments expression specifies any valid expression that evaluates or can be coerced to a character string or numeric value. Leading and trailing blanks are removed, and no message is sent to the SAS log. Restrictions If position is missing a blank space is returned, a warning is written to the SAS log. If position is past the end of the string, an empty string is returned. Notes If the position that you specify is nonpositive, the result is truncated at the beginning, so that the first character of the result is the first character of the string. The length of the result is reduced accordingly. If the sum of position and length is greater than the length of the string, the position is returned until the end of the string.

BOR Function. Google Sites, substrn in sas. Notes If the position that you specify is nonpositive, the result is truncated at the beginning, so that the first character of the result is the first character of the string.

But more interestingly it has got another important use as well. When we use it on the Left side of assignment statement it can be used to replace the part of string in main string. So when used on Right side its extracting part of string and when used on left side it can used for replacing the part of string in original string. This has been demonstrated below;. SAS Code:.

If you do not specify length , the SUBSTRN function returns the substring that extends from the position that you specify to the end of the string. ABS Function. ADDR Function. AIRY Function. ATAN Function. ATAN2 Function. BAND Function. BETA Function. BNOT Function. BOR Function.

The real question is do you want the last three characters, regardless of length, or do you want the substring that starts in the 5th position to the end of the value, or some other rule? The above returns 'abc' because you told it to start in a position before the string and get the following 3 characters. From the documentation : If the position that you specify is non-positive, the result is truncated at the beginning, so that the first character of the result is the first character of the string. Why minus 2 you may ask. The function want a starting position in the second position. If the length of string is 7, then you want positions 5, 6 and 7 assuming you want three characters. So to get 5 you want View solution in original post.

This has been demonstrated below; 1. CDF Logistic Distribution. SAS writes the following output to the log:. If you do not specify length-expression , the SUBSTRN function returns the substring that extends from the position that you specify to the end of the string. BNOT Function. Similarly in the Fourth assignment statement; we can see what happens when we give the invalied start position; which is actually out of bounds of the original string. SAS Studio. SINH Function. ATAN2 Function. Create Sample Dataset.

It can also be used to replace very specific given characters from a string. This is the most common way to use substr function to extract characters from the string.

RANK Function. MIN Function. LCM Function. COSH Function. BYTE Function. CDF Lognormal Distribution. CV Function. General Function Syntax. ATAN2 Function. In the first example, it returns 7 after subtracting 3 from productID. If the length that you specify extends beyond the end of the string, the result is truncated at the end, so that the last character of the result is the last character of the string. Table of content. Similarly in the Fourth assignment statement; we can see what happens when we give the invalied start position; which is actually out of bounds of the original string.
