Large files are common. Large *text* files are not. DOS editors from back when typically had a 64K size limit on the size of a text file you could edit. (IIRC, Win3X versions of Windows Notepad shared that limit.) This was related to Intel segmented architecture. On the 8088 CPU used in the early PCs, a segment was 64K. Text editors held the file you were editing in a segment, assuming it was 64K or less in size. Handling larger files required more complicated code to cross segment boundaries. Most folks editing plain text files were unlikely to deal with one larger than 64K, and most text editors saw no need to handle larger text files. Just how big a file are you likely to need to edit? What sort of file is it, and why is it bigger than 64K? And for that matter, do you need to *edit* it, or just *view* the contents? If you just need to view a large file, you can look at something like the late Vern Buerg's LIST, or Mark Nudelman's LESS command, which originated in Unix and has a DOS port in the FreeDOS repository. Both should handle large files. Vedit was noted for being able to edit enormous files. The was at one point a DOS version, but I have no idea where it might be found now, and you are extremely unlikely to need it. (If you *do*, you are arguably doing it wrong.) As Eric Auer commented, Setedit should edit large files. So should TDE. Both implemented cross segment addressing. > cheers > DS ______ Dennis _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
