Hello World

Using a Call is it necessary? You can call a function without using that keyword right? Second question, which performs faster, using a Call or not?

Rey Sean

推荐答案

指定 CALL 是可选的，并且可以在编程中使用。


这不涉及任何性能问题。

Specifying CALL is optional and is agood practise to use in programming.

That does not involve any performance issue.

指定 CALL ...是编程中使用的好习惯。

Specifying CALL ... is agood practise to use in programming.

这完全是一个意见问题。你很难期望在每个语句之前使用CALL，那么为什么选择特定的呢？


当然，可扩展语言的全部意义在于扩展是无缝地集成到它中，并且不需要使用特殊的编码。

That is entirely a matter of opinion. You would hardly expect to use CALL before every statement, so why pick out particular ones?

Surely the whole point of an extensible language is that the extensions are integrated into it seamlessly, and don''t require special coding to use.

使用Call语句更多的是可读性偏好。


但是要注意，在子例程上使用它是唯一安全的，而不是函数，就像它在函数上使用它会导致返回值被忽略一样。

Using the Call statement is more of a readability preference than anything.

Be aware though, that it''s only safe to use it on Subroutines, not Functions, as when it''s used on Functions it causes the returned value to be ignored.
