Executing vbscript function from anchor tag

TheMSsForum.com: The Microsoft Software Forum

I am trying the execute a VBscript function from an anchor
tag, but seem to be unable to get the syntax correct.
Following is a simple web page that diplays a msgbox.
It works from the button, but not from the Anchor.
Can you you help me?

<HTML>
<INPUT id="cmdWrite" onclick="vbscript:WriteFile('Hello')"
type="button" value="Write File"><BR><BR>
<A HREF="vbscript:WriteFile('Hello')">Say Hello</A>
<SCRIPT LANGUAGE=VBSCRIPT>
Sub WriteFile(Value)
Msgbox "Value=" & Value
End Sub
</SCRIPT>
</HTML>

This appears to be a bug. If you change the WriteFile Sub to a Function and
swap the single and double quotes in the <A> tag then this will work as
expected, It will also work if you leave the Sub in place and substitute the
javascript: protocol in place of the vbscript: protocol. Apparently, you
cannot call a user-defined Sub from a <A> tag using the vbscript: protocol.

<HTML>
<INPUT id="cmdWrite"
onclick='vbscript:WriteFile("Hello")'
type="button"
value="Write File">
<BR><BR>
<A HREF=""
onclick='vbscript:WriteFile("Hello")'>Say Hello

<SCRIPT LANGUAGE=VBSCRIPT>
Sub WriteFile(Value)
Msgbox "Value=" & Value
window.event.returnValue = False

BTW, if you are going to call a VBScript Sub (as opposed to a Function) from
an oneventname attribute, don't use ()s unless you explicitly use the Call
statement:


onclick='vbscript:WriteFile "Hello"'
or
onclick='vbscript:Call WriteFile("Hello")'


That way if you ever modify the Sub to expect more than one argument, you
won't get the infamous 'Cannot use parentheses when calling a Sub' error...
