What does the TRANWORD function do in SAS?

• A. Removes specified characters from a string
• B. Replaces or removes occurrences of a given word
• C. Counts the number of words in a string
• D. Finds the position of a word in a string

Answer: (B)

The TRANWORD function in SAS is designed to replace or remove occurrences of a specific word within a string. This function is particularly useful when you need to cleanse data by replacing certain words with alternatives or when you simply want to remove specific words altogether. For example, if you have a string that contains the phrase "I love programming" and you want to remove the word "love," using the TRANWORD function will allow you to achieve that effectively. It searches the string for the specified word and can replace it with another word or eliminate it from the string based on your requirements. In contrast, other functions mentioned do not serve this purpose. The function that removes specified characters from a string focuses on eliminating non-word characters instead of whole words. Counting words in a string involves a different method and logic, generally using the COUNTW function. Similarly, finding the position of a word in a string is accomplished using the FIND or FINDW functions, which identify where a specified substring appears in a given string. Therefore, understanding the specific functionality of the TRANWORD function clarifies its role in text manipulation within SAS.
