What functionality does the TRANWRD function provide?

The TRANWRD function is specifically designed to replace occurrences of specified words or phrases within a character string with different words or phrases that you provide. This function is useful for string manipulation, allowing you to easily find and replace specific segments of text.

For example, if you have a character string "Hello World" and you want to replace "World" with "SAS," the TRANWRD function would effectively transform the string to "Hello SAS." It operates by searching for an exact match of the word to be replaced and substituting it accordingly, making it a powerful tool for data cleaning and modification tasks.

Other options are not aligned with the functionality of the TRANWRD function. While converting character strings to numeric data, removing special characters, or formatting dates are important data manipulation tasks, they are handled by different functions within SAS, such as INPUT for conversion, COMPRESS for removing characters, and various date formatting functions for date manipulation.
