The general definition of a file does not require that its size have any real meaning, however, unless the data within the file happens to correspond to data within a pool of ...
The EOT character is used in legacy communications protocols by mainframe computer manufacturers such as IBM, Burroughs Corporation, and the BUNCH.Terminal transmission control protocols such as IBM 3270 Poll/Select, or Burroughs TD830 Contention Mode protocol use the EOT character to terminate a communications sequence between two cooperating stations (such as a host multiplexer or Input ...
It allows programs to use the same code to read input from both a terminal and a text file. In the ANSI X3.27-1969 magnetic tape standard, the end of file was indicated by a tape mark , which consisted of a gap of approximately 3.5 inches of tape followed by a single byte containing the character 0x13 (hex) for nine-track tapes and 017 (octal ...
