When I type: > spotread -v -d -yl I get > Result is XYZ ...., D50 Lab: ... But when I add the -x argument, to display Yxy instead of Lab: > spotread -v -d -yl -x I get nothing? I get the same output as though I would have only typed in: > spotread -h Exactly. The same help info. It is as though as adding the -x flag causes spotread to ignore my request completely. Any ideas? Roger Breton
