- !ruby/struct:SM::Flow::P 
 body: Class <tt>IO</tt> is the basis for all input and output in Ruby. An I/O stream may be duplexed (that is, bidirectional), and so may use more than one native operating system stream.
- !ruby/struct:SM::Flow::P 
 body: Many of the examples in this section use class <tt>File</tt>, the only standard subclass of <tt>IO</tt>. The two classes are closely associated.
- !ruby/struct:SM::Flow::P 
 body: As used in this section, portname may take any of the following forms.
- !ruby/object:SM::Flow::LIST 
 contents: 
 - !ruby/struct:SM::Flow::LI 
 label: "*"
 body: A plain string represents a filename suitable for the underlying operating system.
 - !ruby/struct:SM::Flow::LI 
 label: "*"
 body: A string starting with ``<tt>|</tt>'' indicates a subprocess. The remainder of the string following the ``<tt>|</tt>'' is invoked as a process with appropriate input/output channels connected to it.
 - !ruby/struct:SM::Flow::LI 
 label: "*"
 body: A string equal to ``<tt>|-</tt>'' will create another Ruby instance as a subprocess.
 type: :BULLET
- !ruby/struct:SM::Flow::P 
 body: "Ruby will convert pathnames between different operating system conventions if possible. For instance, on a Windows system the filename ``<tt>/gumby/ruby/test.rb</tt>'' will be opened as ``<tt>\\gumby\\ruby\\test.rb</tt>''. When specifying a Windows-style filename in a Ruby string, remember to escape the backslashes:"
- !ruby/struct:SM::Flow::VERB 
 body: " &quot;c:\\gumby\\ruby\\test.rb&quot;\n"
- !ruby/struct:SM::Flow::P 
 body: Our examples here will use the Unix-style forward slashes; <tt>File::SEPARATOR</tt> can be used to get the platform-specific separator character.
- !ruby/struct:SM::Flow::P 
 body: I/O ports may be opened in any one of several different modes, which are shown in this section as mode. The mode may either be a Fixnum or a String. If numeric, it should be one of the operating system specific constants (O_RDONLY, O_WRONLY, O_RDWR, O_APPEND and so on). See man open(2) for more information.
- !ruby/struct:SM::Flow::P 
 body: If the mode is given as a String, it must be one of the values listed in the following table.
- !ruby/struct:SM::Flow::VERB 
 body: " Mode | Meaning\n -----+--------------------------------------------------------\n &quot;r&quot; | Read-only, starts at beginning of file (default mode).\n -----+--------------------------------------------------------\n &quot;r+&quot; | Read-write, starts at beginning of file.\n -----+--------------------------------------------------------\n &quot;w&quot; | Write-only, truncates existing file\n | to zero length or creates a new file for writing.\n -----+--------------------------------------------------------\n &quot;w+&quot; | Read-write, truncates existing file to zero length\n | or creates a new file for reading and writing.\n -----+--------------------------------------------------------\n &quot;a&quot; | Write-only, starts at end of file if file exists,\n | otherwise creates a new file for writing.\n -----+--------------------------------------------------------\n &quot;a+&quot; | Read-write, starts at end of file if file exists,\n | otherwise creates a new file for reading and\n | writing.\n -----+--------------------------------------------------------\n &quot;b&quot; | (DOS/Windows only) Binary file mode (may appear with\n | any of the key letters listed above).\n"
- !ruby/struct:SM::Flow::P 
 body: The global constant ARGF (also accessible as $&lt;) provides an IO-like stream which allows access to all files mentioned on the command line (or STDIN if no files are mentioned). ARGF provides the methods <tt>#path</tt> and <tt>#filename</tt> to access the name of the file currently being read.
