First of all, your premise is false. There are languages that use space as a separator (lisp, ML, haskell, possibly others).

The reason that most languages don't is probably that a) <code>f(x,y)</code> is the notation most people are used to from mathematics and b) using spaces leads to lots of nested parentheses (also called "the lisp effect").

Absolutely not. What about this function call:

<pre><code> function(a, b - c);
</code></pre>

How would that look with a space instead of the comma?

<pre><code> function(a b - c);
</code></pre>

Does that mean <code>function(a, b - c);</code> or <code>function(a, b, -c);</code>? The use of the comma presumably comes from mathematics, where commas have been used to separate function parameters for centuries.

blocks|key|888205|text|类Lisp语言使用：(f+arg1+arg2+arg3)，这实际上就是您所要求的。类ML语言使用连接来应用curried参数，因此您可以编写f+arg1+arg2+arg3。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|888206|entityMap^0|A|I|1Y|G|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

Lisp-like languages use: <code>(f arg1 arg2 arg3)</code> which is essentially what you're asking for.
ML-like languages use concatenation to apply curried arguments, so you would write <code>f arg1 arg2 arg3</code>.

blocks|key|2743296|text|Tcl使用空格作为传递给命令的单词之间的分隔符。如果它有一个复合参数，则必须用括号括起来或以其他方式引用。请注意，即使在那里，您也会发现使用逗号作为分隔符-仅在表达式语法中-但这是因为这种表示法在编程之外是常见的。数学已经用这种方式编写n元函数应用程序很长一段时间了；计算(特别是Fortran)只是借用。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2743297|entityMap|0|LINK|mutability|MUTABLE|url|http://www.tcl.tk/^0|0|3|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

<a href="http://www.tcl.tk/" rel="nofollow noreferrer">Tcl</a> uses space as a separator between words passed to commands. Where it has a composite argument, that has to be bracketed or otherwise quoted. Mind you, even there you will find the use of commas as separators – in expression syntax only – but that's because the notation is in common use outside of programming. Mathematics has written n-ary function applications that way for a very long time; computing (notably Fortran) just borrowed.

blocks|key|1637049|text|你不需要比我们的大多数自然语言看得更远，就会发现逗号用于列表中的分隔项。因此，对于第一次学习编程语言的人来说，使用逗号以外的任何东西来枚举参数都是意想不到的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1637050|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You don't have to look further than most of our natural languages to see that comma is used for separation items in lists. So, using anything other than comma for enumerating parameters would be unexpected for anyone learning a programming language for the first time.

blocks|key|890491|text|已经指出了许多历史原因。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|890492|此外，这是因为在,充当分隔符的大多数语言中，空格序列在很大程度上被忽略了，或者更准确地说，尽管它们可以分隔tokens，但它们本身并不充当标记。这对于所有从C派生语法的语言来说都是如此。空格序列很像空词，用空词来分隔任何东西可能不是最好的想法。|offset|length|style|CODE|890493|此外，我认为它更清晰，更容易阅读。为什么要让空格作为真正有意义的分隔符呢?空格是看不见的字符，本质上除了格式化之外什么也没有。它只会引入歧义。一个例子是由Carl提供的。|890494|第二个是f(a+(b+%2B+c))。现在是f(a(b%2Bc))还是f(a,+b%2Bc)|890495|JavaScript的创建者有一个非常有用的想法，类似于你的想法，它产生了同样的问题。这个想法是，如果语句完整，ENTER也可以充当;。请注意：|890496|function+a()+{

There's a number of historical reasons already pointed out.

Also, it's because in most languages, where <code>,</code> serves as separator, whitespace sequences are largely ignored, or to be more exact, although they may separate <a href="http://en.wikipedia.org/wiki/Token_%28parser%29#Token" rel="noreferrer">tokens</a>, they do not act as tokens themselves. This is moreless true for all languages deriving their syntax from C. A sequence of whitespaces is much like the empty word and having the empty word delimit anything probably is not the best of ideas.

Also, I think it is clearer and easier to read. Why have whitespaces, which are invisible characters, and essentially serve nothing but the purpose of formatting, as really meaningful delimiters. It only introduces ambiguity. One example is that provided by Carl.

A second would <code>f(a (b + c))</code>. Now is that <code>f(a(b+c))</code> or <code>f(a, b+c)</code>?

The creators of JavaScript had a very useful idea, similar to yours, which yields just the same problems. The idea was, that ENTER could also serve as <code>;</code>, if the statement was complete. Observe:

<pre><code>function a() {
 return "some really long string or expression or whatsoever";
}

function b() {
 return 
 "some really long string or expression or whatsoever";
}
alert(a());//"some really long string or expression or whatsoever"
alert(b());//"undefined" or "null" or whatever, because 'return;' is a valid statement
</code></pre>

As a matter of fact, I sometimes tend to use the latter notation in languages, that do not have this 'feature'. JavaScript forces a way to format my code upon me, because someone had the cool idea, of using ENTER instead of <code>;</code>.

I think, there is a number of good reasons why some languages are the way they are. Especially in dynamic languages (as PHP), where there's no compile time check, where the compiler could warn you, that the way it resolved an ambiguity as given above, doesn't match the signature of the call you want to make. You'd have a lot of weird runtime errors and a really hard life.

There are languages, which allow this, but there's a number of reasons, why they do so. First and foremost, because a bunch of very clever people sat down and spent quite some time designing a language and then discovered, that its syntax makes the <code>,</code> obsolete most of the time, and thus took the decision to eliminate it.

blocks|key|4151447|text|这可能听起来有点明智，但我猜这与大多数地球上的语言(英语、法语和其他为数不多的语言)使用它的原因相同;-)而且，它对大多数人来说都是直观的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4151448|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Haskell doesn't use commas.

Example

<pre><code>multList :: [Int] -&gt; Int -&gt; [Int]
multList (x : xs) y = (x * y) : (multList xs y) 
multList [] _ = []
</code></pre>

The reason for using commas in C/C++ is that reading a long argument list without a separator can be difficult without commas

Try reading this

<pre><code>void foo(void * ptr point &amp; * big list&lt;pointers&lt;point&gt; &gt; * t)
</code></pre>

commas are useful like spaces are. In Latin nothing was written with spaces, periods, or lower case letters.

blocks|key|2743222|text|这不是真的。有些语言不使用逗号。在编程构造之前，函数一直是数学概念，因此一些语言保留了旧的表示法。比大多数较新的语言都受到C语言的启发(Javascript，Java，C#，PHP也是如此，它们共享一些正式的规则，比如逗号)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2743223|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This is not true. Some languages don't use commas. Functions have been Maths concepts before programming constructs, so some languages keep the old notation. Than most of the newer has been inspired by C (Javascript, Java, C#, PHP too, they share some formal rules like comma).

blocks|key|888421|text|虽然有些语言确实使用空格，但使用逗号可以避免不需要括号的歧义情况。一个更有趣的问题可能是，为什么C使用与"a+then+b“操作符相同的字符作为分隔符；后一个问题在某些方面更有趣，因为C字符集还有另外三个没有出现在任何上下文中的字符(美元符号、商业-+at和grave，我知道其中至少有一个(美元符号)可以追溯到40个字符的穿孔卡集。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|888422|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

While some languages do use spaces, using a comma avoids ambiguous situations without the need for parentheses. A more interesting question might be why C uses the same character as a separator as is used for the "a then b" operator; the latter question is in some ways more interesting given that the C character set has at three other characters that do not appear in any context (dollar sign, commercial-at, and grave, and I know at least one of those (the dollar sign) dates back to the 40-character punchcard set.

<blockquote>

</blockquote>

In natural languages that include comma in their script, that character is used to separate things. For instance, if you where to enumerate fruits, you'd write: <code>"lemon, orange, strawberry, grape"</code> That is, using comma. 

Hence, using comma to separate parameters in a function is more natural that using other character ( | for instance ) 

Consider: 

<pre><code>someFunction( name, age, location ) 
</code></pre>

vs. 

someFunction( name|age|location ) 

<blockquote>
 Why don't they use just spaces instead?

Thats possible. Lisp does it. 

The main reason is, space, is already used to separate tokens, and it's easier not to assign an extra functionality.

I have programmed in quite a few languages and while the comma does not rule supreme it is certainly in front. The comma is good because it is a visible character so that script can be compressed by removing spaces without breaking things. If you have space then you can have tabs and that can be a pain in the ... There are issues with new-lines and spaces at the end of a line. Give me a comma any day, you can see it and you know what it does. Spaces are for readability (generally) and commas are part of syntax.
