Try adding something like export DISPLAY=localhost:0 or setenv DISPLAY localhost:0 depending on which shell you use and where your X server is, to the script run by cron. Connecting to the X server is done automatically to ensure that system/view/screen-face/size is set correctly. That's why you see the error. View/Pro is not really intended for use with non-interactive scripts. That's what Command is for.

Well, the script that I > wrote works great on View/Pro, but it bombs out under Command. I get an > error saying that there is some kind of TCP socket listen error when I try to > FTP.

No. Sounds like your user.r is wrong. You are probably using different settings (for proxy or ftp-passive) for Command than you are using for View/Pro. If you installed Command and View in different places then your user.r might just be in the wrong directory.

Asking on the mailing list is usually the easiest way. We do respond through feedback as well, and sometimes more quickly, but have fallen a little behind there recently, partly due to vacations. Sorry for that. -- Holger Kruse [holger--rebol--com]
