I think you're referring to T, a freeware editor by Tim Baldwin at IBM's UK labs: http://texteditors.org/cgi-bin/wiki.pl?T I have it here. Like various other DOS editors, it edits files up the the limit of conventional memory. > Using elvis 2.2, I was able to view and edit files in DR-DOS above 1.5 MB, > but scrolling through a file of 3 MB was prohibitively slow; no such problem > in Linux. > > Maybe that was because DOS is not really made for large RAM. Editors I'm aware of that ran under DOS and edited really large files used spill files, keeping what would fit in memory in RAM, and the rest on disk, swapping to disk as required. On DOS machines, that was *slow*. DOS wasn't made for large RAM. The 8088 CPU machines on which it ran had an address space of 1MB, and 640K of that was usable by DOS. If you had more RAM than that installed, you needed it seen as EMS or XMS, and accessed by convoluted programming. > Still, I prefer to switch to Linux, FreeBSD or NetBSD to edit anything > serious, using vi. > > Apparently DOS, including FreeDOS, works better on an older computer than on > a modern computer. Yes. It was designed for older machines. It simply can't use most of what newer ones offer. > Tom ______ Dennis https://plus.google.com/u/0/105128793974319004519 ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
