sure, send it over...

To may work to pass a variable back but I'm not sure if it works
on all /bin/sh out there (at this point everyone know I'm a bit weary
of Solaris and Digital Unix)

set it up this way (YMMV):

exec < foo
count=0
while read line
do
        count=`expr $count + 1`
done
echo $count
exec <&2

A pseudo subshell is always create when input is redirected into
a while/for/until/do/case statements (and when output is also
redirected from them).

So by doing exec < foo  you specify that all input will be from
the file foo and no input needs to be redirected on the while loop
which executes in the same subshell.

Gee, I'd totally forgotten about this, that was a good question :)

Humm, I'm surprised Henrik didn't complain about this ;)

But it doesn't really matter before each ALT tag is made up of
service:color so you don't need the column heading in Lynx.

Yup, but until somebody tells me that it doesn't work, it's staying
that way ...

Thanks for that one

I know, maybe would could complain to W3C :)

If it looks ugly, I want no part of it ! ;)
But what problem are you solving ?

I'll have to try that one.

How's it behave with 2.0 browsers ?

Yeah and Sun's getting into that business with Jini ;)  We've got
