Dear Erixon, I saw your mail in the list about some useful document of listserv. ............................ From: Mignon Erixon-Stanford, Academic Systems Head ................................................. ...................................................... so I wrote a quickie little technote which I distribute to new users. It's formatted, but I can send the script file and you're welcome to make changes. I can send a hardcopy in the post if anyone is interested. ............................................................ I am a research student at Tata Institute of Fundamental Research, Bombay,INDIA. I am also looking for the same type of document. So it will be be helpful if you can send me a copy of the same in either form ( by E-mail or post). Thanks.
