You could do something like this:
<html>
<head>
<title>Untitled</title>
<SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript">
<!--
function fncCheckLength() {
document.forms[0].txtLength.value =
document.forms[0].txtTextArea.value.length
if (document.forms[0].txtTextArea.value.length >= 255) {
alert("You have reached the limit of 255 characters for this
text box. Anything you tpe beyond this point will be truncated.")
}
return false
}
//-->
</SCRIPT>
<META NAME="generator" CONTENT="Allaire HomeSite 4.0">
</head>
<body>
<form action="" method="post">
<textarea name="txtTextArea" wrap="soft" rows="5" cols="30"
onkeyup="fncCheckLength();"></textarea><br>
<input type="Text" disabled width="4" value="0" name="txtLength">
</form>
</body>
</html>

| len(form.specialrequest) returns the number of characters.
|
| If you want to automatically chop off at 255 rather than letting them
| re-enter, then you'll want to use the Mid() function as well.
|
| What would be very nice (and I'd love to see an example from someone who
| already knows how), would be to use JavaScript to alert and hopefully stop
| the user when they've typed in characer 256.
