I still see a quoting problem here...
At least, when I try this-- it doesn't work.
I have only been able to get awk to work properly if I use
single quotes and not double quotes.
As a side question, does ANYONE have any bourne shell routines which do
math... reasonably effeciently? (For numbers > 1000?)
