If the program needs to reroute the flow of control to the calling subroutine or the calling function on the occurrence of some specific condition. Redirecting execution flow to the parent (calling) subroutine from the called subroutine

Returning control to keyboard once the match is found.

Performing validation checking on input data.

The below code snippet defines a function findindex() where the return command is used with 2 purposes:

If a program needs the user to take action on the occurrence of some specific condition, the current subroutine or function can be called directly without being triggered by any parent sub routine, and the flow of control returns to the command prompt or the keyboard when the command ‘return’ is executed. Some of the important use cases are discussed below. It can also be used for data validity checking functionality. Return command is used in different conditions based on the technical requirement of the program.
