Character 26 is <kbd>Ctrl</kbd><kbd>Z</kbd>, [the substitute character][1] in ASCII, which is [the end-of-file marker][2] in CP/M, DOS, and descendants. Many tools developed for those operating systems will stop processing files when they encounter this character. So on a typical 80×25 DOS screen, with `ANSI.SYS` or equivalent, TYPE yourfile.ans would output the file to the screen, relying on `ANSI.SYS` to interpret the ANSI escapes, and stopping at the end-of-file marker, so [the SAUCE records don’t appear on-screen][3].
