<body>
$WBSETV[loopcounter|0]
$WBWHILE[$wbgetv[loopcounter]<=10|
The loopcounter value is:$wbgetv[loopcounter]<br>
$WBIV[loopcounter]
]
Loop ended, loopcounter value is $wbgetv[loopcounter]!
</body>
</html>

The loopcounter value is:4
The loopcounter value is:5
The loopcounter value is:6
The loopcounter value is:7
The loopcounter value is:8
The loopcounter value is:9
