I thought so too, but then why does the cfscript block act differently
then the tagged block ... or am I missing something

um... well this:
<script language="_javascript_" type="text/_javascript_">
for(i=0;i<=10;i++)
{
for(i=0;i<=10;i++)
{
document.write(i + "<br>");
}
}
</script>
acts like the cfscript looping to 10 only as I would expect - not to 10 10 times

I am going to rewrite it as I have never seen variable reuse on inner
loops, and I don't think it works in most languages - but as you
pointed out I guess it works that way on Fortran. But if it is indeed
a feature, how do you get to the outer loop variable - if its scoped
what is the scope name?

yeah, thats how I was taught (I didn't write the fragment in question
- nor would I ever do that even if it is legal cfml)

But why only in the tag syntax? ... oh well I guess its unanswerable :-/

Thanks for the input Dick
