Control Break Statement Of Work For Free

The prerequisite for using control break statements is that the internal table must be sorted in the exact order of the components of its row type ing to the processing sequence in which the LOOP loop reads the rows of the internal table.

The break statement can be used with a labeled loop. The labeled break statement can be used to terminate that labeled loop execution further. That labeled loop may be inner or at the top label in the statements. Break statement makes the loop more flexible & provides more power to it.

Control Break Statements are used to control the sequential execution of the statements inside loop and end loop. This can be achieved by using the break statements and it is applicable only inside the loop and End loop.

When a break statement is encountered inside a loop, the loop is immediately terminated and the program control resumes at the next statement following the loop. It can be used to terminate a case in the switch statement (covered in the next chapter).

The break statement is frequently used to terminate the processing of a particular case within a switch statement. Lack of an enclosing iterative or switch statement generates an error.

Break Statement is a loop control statement that is used to terminate the loop. As soon as the break statement is encountered from within a loop, the loop iterations stop there, and control returns from the loop immediately to the first statement after the loop.

Control levels are defined by the beginning or end of a group of rows with the same content in the component compi (where i = 1, 2, and so on) and in the components on the left of compi. The content of these components determines the control key.

Overusing break statements is also bad practice because it introduces more exit points. We generally want to keep exit points to a minimum since multiple exit points complicate our logic and make it more difficult to comprehend code.

Control break processing is used to execute a piece of code whenever a specific condition in the data is detected during the processing of internal table loop. The following control break statements are available with in LOOP and ENDLOOP. The code between AT NEW and ENDAT is executed only during the first loop pass.

The statements in a processing block are organized in control structures. These define statement blocks and control the progress of the program within a processing block. They determine the conditions for processing statement blocks and how often this happens. Control structures can be nested.
