Given the following code, which of the following statements are correct? Select two correct answers.

The statement asserting that the FOR construct defines a loop that runs over the content of source_itab is correct because, in ABAP, the FOR statement is typically employed to iterate over internal tables. This allows the programmer to process each entry in the specified internal table sequentially. Therefore, when using FOR with the given internal table (source_itab), it will indeed loop through each record, enabling operations to be performed on the content of that table during each iteration.

Additionally, the statement that row is only visible within the loop is also correct. In the context of the FOR loop in ABAP, the iteration variable (in this case, row) is defined within the scope of the loop. This means that it cannot be accessed outside of that loop, ensuring that the variable maintains its intended scope, which is essential for controlling variable visibility and minimizing the risk of unintended side effects in other parts of the program.

Both points highlight important aspects of variable scope and control structures in ABAP programming, leading to cleaner and more maintainable code.
