2048 characters in single words, tag names, and filenames (this must be at least as large as the LITLEN limit set in the SGML parser declaration file html.decl);
100 levels of list and environment nesting (this must be at least as large as the TAGLVL limit set in the SGML parser declaration file html.decl);
6 simultaneously open files (stdin, stderr, and stdout, plus the style catalog file, and two style files, allowing at least two levels of style file nesting).
These are ample for any realistic document: they support the longest legal file paths in all major current operating systems, World-Wide Web URLs, and HTML tags named after 58-letter Welsh towns like Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch, yet will still work on the smallest personal computer operating systems.
There is no limit on the size of input or output files and lines, other than that imposed by physical storage limits of the host file system and the computer address space.
