I have to log in via phonelines or networks and the delays both with UNICOS swapping and network make working with VI (say) almost impossible. Having to wait a few seconds for responses leads to real confusion. And editing mistakes. For small editing situations (changing a few syntax errors for example) its alright. But any extensive restructuring of a program I'd rather edit it on my workstation and use KERMIT to upload to the Cray. The problem is trying to do critical work (like editing) in a timesharing environment. What I have done is build a small testbed in my Apollo so I can develop codes locally and only later bring them to the Cray. But then again, my Cray isn't in the next room. (Its 3Kmiles away). -- ...Richard Friedman rchrd@well.uucp (Pacific-Sierra Research/Berkeley, CA.) also: {lll-crg,pacbell,hplabs}!well!rchrd
