you could be right...my problem is I can't enclose the sed string in
single quotes because the variables won't expand and I find that just
doing this...

sed -i "s|$dc|$rc|g" ARsalesorderdetails.csv

fails and still leaves me with this...

1,6066,"Q1500T3/CL/120V",2," 6.99 ",2,,,"2007-01-09",1,,,

so I'm strugging with various ways...

sed -i "s|$(dc)|$(rc)|g" ARsalesorderdetails.csv # doesn't work
or the curly braces to try to keep the string together
