[gradsusr] How to output contour to a txt/dat file

[Taixia]

Hi Jennifer,
Thanks a lot for your reply.
Problem still exists,forgive a Grads beginner. The data I used is the NECP
5 years average air temperature, I'd like get the zero degree temperature
line. After "set clevs 0", I got the contours graphic (see attachment). But
I still cannot get the output file as your steps. Could you please have a
look at the attachments and help?
