return expression In addition to specifying a value, return causes the immediate termination of the subroutine. A function that has figured out what to return but doesn't want to return yet can always assign the
In some languages, there’s a clear difference between a routine or procedure and a function. Sometimes that difference is so strong that you need to use a specific keyword to define a procedure or subroutine and another keyword to define a function. For example the Visual Basic programming ...
Control can be transferred to the finally clause (the finally subroutine can be invoked) in several different ways. If the try clause completes normally, the finally subroutine is invoked via a jsr instruction before evaluating the next expression. A break or continue inside the try clause that ...
If a RESULT block is present, it overrides the normal ``last expression evaluated'' logic for subroutine return values, and also is executed in the context of the caller.For example, suppose we want to execute a coderef as a transaction against a database handle:...

Frankly it does exactly what it does in any other programming language, which is exit a subroutine or a main program. it may or may not return a value which could be a number or a list of values or a string. ☀️☀️
the method more clearly expresses its intend to branch to a subroutine and simply return its result in any sane language, the method does not compile if the branches do not cover all possibilities (in Java, this can also be achieved with a single return if the variable is not initialized ...
return语句返回的是其所在方法的控制权,即终止该方法的此次执行; 而迭代器方法运行到 yield return 语句时,会返回一个 expression,并保留当前在代码中的位置。 下次调用迭代器函数时,将从该位置重新开始执行。 2、可以在同一个方法中同时使用多个yield return语句,同时返回多个值; 但是不能在同一个方法中用return...

In computer programming, a return statement causes execution to leave the current subroutine and resume at the point in the code immediately after where the subroutine was called, known as its return address. The return address is usually saved on the process's call stack as part of the ...
