Final Answer :
True
Explanation :
When a subroutine is called, the program temporarily jumps to the specified subroutine and executes its instructions. Once the subroutine is completed, the program returns to the point where the subroutine was called and continues execution from there. No rungs in the main program are skipped over during this process.
