扔的历史？ [英] The history of throw?
问题描述
我刚刚阅读_The_GNU_Emacs_Lisp_Reference_Manual_
on / Explicit / / Nonlocal / /退出/ [*]中的部分，不得不想知道首先使用什么语言
介绍了投掷，捕捉和放松。请注意，
（Emacs）Lisp没有称为异常的东西，也没有
''try''关键字。所以我们在C ++中找到的肯定不会从Lisp
中获取，如果它确实受到了Lisp的影响。我已经读过
，堆栈展开的概念是从Lisp借来的。有人
知道这段历史的细节吗？

可能是PL / I，大约在1968年。

Fortran。

I just read the section in _The_GNU_Emacs_Lisp_Reference_Manual_
on /Explicit/ /Nonlocal/ /Exits/[*] and had to wonder what language first
introduced the idea of throwing, catching, and unwinding. Note that
(Emacs) Lisp does not have something called ''exception'', nor does it have a
''try'' keyword. So what we find in C++ is certainly not taken from Lisp
without modification if indeed it was influenced by Lisp at all. I''ve read
that the concept of ''stack unwinding'' was borrowed from Lisp. Does anybody
know the details of this history?

Probably PL/I, in approximately 1968.

"The alternate RETURN allows a procedure to return
to one of the several labelled statenebts in the calling program unit
dependent upon the value of an integer variable."
