K-shell variables & Do-loops

[Dallas Braxton]

I'm writing a shel script using K-shell with do loops,
and I want to be able to "export" variables from the loop
to the main body. Example:

var1=yes
# ...
i=1
while i<2
do
# ...
	var1=no
	i=i+1
# ...
done
echo $var1

I get "yes".  How does one get "no"?
