Which statement is used to divide a character string into several substrings?

The statement used to divide a character string into several substrings is SPLIT. This command in ABAP allows you to take a single string and break it down into multiple components based on specified delimiters. It can take a string and split it into an internal table or multiple variables, which makes it particularly useful when dealing with strings of varying lengths or formats, especially when you need to process data in segments.

SPLIT can handle different types of delimiters, giving developers flexibility in managing string data. For example, if you have a string that contains comma-separated values, using the SPLIT statement allows you to easily extract each value into a desired format for further processing.

The other options serve different purposes: CONCATENATE is used to join multiple strings together, WRITE is meant for outputting data to the screen or logs, and REPLACE is utilized for replacing parts of a string with different content. Each of these commands does not facilitate the division of a string into smaller parts, which is why SPLIT is the appropriate choice for this particular task.
