JScript "Main" function

When writing a standalone VBScript script, the first function called is Sub Main, just as in VB. What is the equivalent of Sub Main when writing standalone JScript scripts?

As I stated in the question, I am not referring to HTML-embedded scripts; I am asking about standalone scripts. Also, I did not ask what a function looks like in JScript, but what the *main* function looks like.

When developing your ActiveX Script Host you must specify which function you want to use as "main" as in the snipet below:

...
//get the dispatch interface to the engine and
// call the procedure named "main"
hr = pIas->GetScriptDispatch (0, &pIDisp);
LPOLESTR szMain = OLESTR ("main");
DISPID dispid;
hr = pIDisp->GetIDsOfNames (IID_NULL, &szMain, 1, 9, &dispid);
DISPPARAMS params = {0, 0, 0, 0};
hr = pIDisp->Invoke (dispid, IID_NULL, 9, DISPATCH_METHOD, &params, 0, 0, 0);
...

Technically you can specify anything you want, but "main" is a good default as it conforms to VBScript standards, whereas JScript doesn't have a standard (that I know of, at any rate). This would mean that the JScript:

function main()
{
...
}

would be equivalent to VBScript:

public sub main()
...
end sub

You would want to be certain to document this for your end-users.

JScript has no main function, although if a

<script language="VBScript">

was used, you could define a main function. For
JavaScript, use the onLoad attribute in the <body>
tag and define a function to call (this will work
for JScript and JavaScript BTW).
