how to change context view (preview) format

[rjshelq]

OK thanks guys. How can I look at "future" array indexes while in a loop?

For example, in the code which Kai provided, there is a loop called <loop $hitOffsets> which is happily going through each value of $hitOffsets. If I'm on the Nth time through that loop, how can I examine the (N+1) value of $hitOffsets ?

You can't look ahead as such. You'll probably have to loop over everything twice, first to decide what to do then to do it.
