2E - EOLN and EOF (author: Tao Yue, state: unchanged)
EOLN is a Boolean function that is TRUE when you have reached the end of a line in an open input file.
eoln (file_variable)
If you want to test to see if the standard input (the keyboard) is at an end-of-line, simply issue eoln without any parameters. This is similar to the way in which read and write use the console (keyboard and screen) if called without a file parameter.
eoln
EOF is a Boolean function that is TRUE when you have reached the end of the file.
eof (file_variable)
Usually, you don't type the end-of-file character from the keyboard. On DOS/Windows machines, the character is Control-Z. On UNIX/Linux machines, the character is Control-D.
