Even more ironically, that statement is both true and false. =8^)

It is true that Unix files do not end with a particular character, and
as such there is no EOF character.  However, when typing on a
terminal, there is, in fact, a way to type EOF.  How that is done is
revealed by stty -a:

  speed 38400 baud; rows 64; columns 160; line = 0;
  intr = ^C; quit = ^\; erase = ^H; kill = ^U; eof = ^D; eol = <undef>;
  eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W;
  [much other output snipped]

Here (line 2), we see that EOF is signified by ^D, which is the normal
default on most Unix-like operating systems.  It can be changed with
stty about as easily as it can be displayed.

FWIW, until fairly recently, I've only ever heard it called "here
documents" by Perl programmers...  In every Unix-related class I've
taken prior to that, whether at a university or at a vendor's training
facility, it was referred to as "in-line redirection" instead.
