How do I find a character in SAS?

What is the difference between find and index function in SAS?
The FIND function and the INDEX function both search for substrings of characters in a character string. However, the INDEX function does not have the modifier nor the start-position arguments.
How do you check if a string contains a character in SAS?
The SAS find() function allows us to check and see if a character variable contains a given substring of characters. find() takes in two required arguments, the character variable you want to check and a given substring of characters.
How do I scan a function in SAS?
The most basic use of the SCAN function requires only two arguments. After specifying SCAN and an open parenthesis, the first part of the function is to specify the character string that you are planning to select words from. This can be either a variable or an explicit character string.
What is Prxmatch in SAS?
1. PRXMATCH. Searches for a pattern match and returns the position at which the pattern is found. PRXMATCH (perl-regular-expression, variable_name) It returns the position at which the string begins.
What is Anyalpha in SAS?
The ANYALPHA function searches a string for the first occurrence of any character that is an uppercase or lowercase letter. If such a character is found, ANYALPHA returns the position in the string of that character. If no such character is found, ANYALPHA returns a value of 0.
What is the use of find () in string give example?
Python String find() method returns the lowest index or first occurrence of the substring if it is found in a given string. If it is not found then it returns -1. Parameters: sub: It is the substring that needs to be searched in the given string.
How do I search for a specific word in SAS?
You can use the FIND function in SAS to find the position of the first occurrence of some substring within a string. data new_data; set original_data; first_occurrence = find(variable_name, “string”, “i”); run; The “i” argument tells SAS to ignore the case when searching for the substring.
How do I extract a substring in SAS?

What are SAS functions?
A function is a component of the SAS programming language that can accept arguments, perform a computation or other operation, and return a value. Functions return either numeric or character results. The value that is returned can be used in an assignment statement or elsewhere in expressions.
What is Prxparse?
The PRXPARSE function returns a pattern identifier number that is used by other Perl functions and CALL routines to match patterns. If an error occurs in parsing the regular expression, SAS returns a missing value. PRXPARSE uses metacharacters in constructing a Perl regular expression.

- Specify the input variable that contains the character you want to replace.

How do I find a word in a string?
To find a word in the string, we are using indexOf() and contains() methods of String class. The indexOf() method is used to find an index of the specified substring in the present string. It returns a positive integer as an index if substring found else returns -1.
How do I extract a word in SAS?

How to Extract the Last Character from a SAS String
- You can use the SUBSTR() function in combination with the LENGTH() or REVERSE() function to extract the last character from a string in SAS.
- The first method to get the last character from a string combines the power of the SUBSTR() function and the LENGTH() function.
