Thanks for the reply, and a possible solution.

The examples in the FAQ do work for the their examples, but I can't figure
out a clean way to implement it with a while loop when reading in lines from
the output of a piped command(s).

Your solution also works, but would be very messy if I wanted to use $var
much later in the script as I would need the rest of the script kept in the
{ }.

I suppose, after years of using the ksh I'm missing the (in my opinion) the
clearer 'command | while read....' solution.
