Need help: Error messages

[deleted_user]

I use SAS in UNIX (on the server of my university) through SSH shell to run some programs for research. It works great before. However, since yesterday, I've started to get error messages. For example, I have a sas program file named 'x.sas'; previously I could run this file by type command '>sas x.sas', but now it gives following messages:

ERROR: Cannot open X display. Check display name/server access authorization.
ERROR: Explorer failed to initialize.
ERROR: Cannot open X display. Check display name/server access authorization.
ERROR: Cannot open X display. Check display name/server access authorization.
ERROR: Explorer failed to initialize.
ERROR: Device does not support full-screen.
ERROR: Device does not support full-screen.

The 'x.sas' file doesn't include any 'proc import' or 'proc export' or anything that might evoke the error message. Actually, 'x.sas' is an old file. I could run it properly by 'sas x.sas' command previously, but can not now.

I tried '>unsetenv DISPLAY', but it doesn't work. However, '>sas -nodms x.sas' seemed work. But it makes no sense cause since I could properly run SAS on our server previously without the option '-nodms'. Why it becomes necessary now, and how comes this option can solve this problem?

I didn't change any setting in the SSH shell or anything on my PC. I'm not the only user has this problem; my professor also meet this problem. Can your experts help me to diagnose the problem? and how to solve it eventually? Thanks!
