They are not very kind to newbies. It can be done in JavaScript, but this
works with just HTML:

<html>
<head><title>SetTrue</title>
</head>
<body>
<input type="hidden" name="myVar" value=false>
myVar: <input type=text name=myTextBox
value="Click for myVar"
OnClick="myTextBox.value=myVar.value" ></input>
<input type="button" name="btSetTrue"
value="Set True" onClick="myVar.value=true;
myTextBox.value=myVar.value;" </input>
</body>
</html>

Well, I was going to dispute that, since I thought the <script
type=text/javascript> tags were needed, but I found that the browser warned
about "scripts or active controls" even with just the simple event handlers
in the input controls. However the script may not necessarily be JavaScript
unless the browser automatically chooses a script engine that matches the
syntax. This example may also be done using vbScript:

<input type="hidden" name="myVar" value=false>
myVar: <input type=text name=myTextBox
value="Click for myVar"
OnClick="myTextBox.value=myVar.value" />
<input type="button" name="btSetTrue"
value="Set True" onClick="btSetTrue.value = setDone() " />
<script type="text/vbscript">
Function setDone()
myVar.value=true
myTextBox.value=myVar.value
setDone = "Done"
End Function
</script>

Thanks for the clarification. I learned something.

Not in my browser it won't. Do not use vbScript for on the web...we are
trying to rid the shackles of IE6.
