I hear that you can run NeWS on a Mac under the MacOS Finder. What can you do with NeWS on a Mac besides using it as a NeWS Server and connecting to another machine? I mean, can you develop NeWS software on a stand-alone Mac? I don't understand how this can be done with an operating system without true multitasking. As I see it, the NeWS server is running on a Mac waiting for a request. But since it is the only process, it must wait for an event from a serial port or network before it initiates anything. Maybe you can send commands to the server using psh, but how can you edit a file or program and test it without using another computer? Am I missing something? Or is NeWS on the MacOS useless in a stand-alone environment? -- Bruce G. Barnett <barnett@ge-crd.ARPA> <barnett@steinmetz.UUCP> uunet!steinmetz!barnett

One can develop a certain class of NeWS software on a standalone Mac: that class of applications that runs in the NeWS server as its own lightweight PostScript process with any necessary scheduling handled by the NeWS server. This is how NeWS "desk accessory" applications like calcul, puzzle, itemdemo, rotate, spirograph, world, and friends work. Note that window systems like X can support none of this class of applications. All X applications really, truly do require their own address spaces on some machine somewhere; whether on the same machine where the server runs, or on some other host across an inter-process communication channel of some sort. -=- Bob Sutterfield, Department of Computer and Information Science The Ohio State University; 2036 Neil Ave. Columbus OH USA 43210-1277 bob@cis.ohio-state.edu or ...!cbosgd!osu-cis!bob

Do you have a lite-weight editor that runs under NeWS? (Actually sounds like the great idea). -- Bruce G. Barnett <barnett@ge-crd.ARPA> <barnett@steinmetz.UUCP> uunet!steinmetz!barnett
