  \includelineno awk21.cpp
 
+Customizing the console I/O is not much different in C++. When using the
+QSE::StdAwk class, you can inherit the class and implement these five methods:
+
+ - int openConsole (Console& io);
+ - int closeConsole (Console& io);
+ - int flushConsole (Console& io);
+ - int nextConsole (Console& io);
+ - ssize_t readConsole (Console& io, char_t* data, size_t size);
+ - ssize_t writeConsole (Console& io, const char_t* data, size_t size);
+
+The sample below shows how to do it to use a string as the console input
+and store the console output to a string buffer.
+
+ \includelineno awk22.cpp
+
+Alternatively, you can choose to implement QSE::Awk::Console::Handler
+and call QSE::Awk::setConsoleHandler() with the implemented handler.
+This way, you do not need to inherit QSE::Awk or QSE::StdAwk.
+The sample here shows how to customize the console I/O by implementing
+QSE::Awk::Console::Handler. It also shows how to run the same script
+over two different data streams in a row.

+Overview
+--------
 A stream editor is a non-interactive text editing tool commonly used
 on Unix environment. It reads text from an input stream, stores it to
 pattern space, manipulates the pattern space by applying a set of editing
 commands, and writes the pattern space to an output stream. Typically, the
 input and output streams are a console or a file. 
 
-@b QSESED is an embeddable stream editor that supports most of 
-the conventional sed commands and implements input and output streams as a 
-callback function: 
-
-- #qse_sed_t - C type that encapsulates a stream editor
-- QSE::Sed - C++ class that wraps #qse_sed_t
-- QSE::StdSed - C++ child class of QSE::Sed that implements standard input and output streams

+Commands
+--------
 
 A sed command is composed of:
 
-- line selector (optional)
-- ! (optional)
-- command code
-- command arguments (optional, dependent on command code)
+ - line selector (optional)
+ - ! (optional)
+ - command code
+ - command arguments (optional, dependent on command code)
 
 A line selector selects input lines to apply a command to and has the following
 forms:
-- address - specify a single address
-- address,address - specify an address range 
-- start~step - specify a starting line and a step. 
-               #QSE_SED_STARTSTEP enables this form.
+ - address - specify a single address
+ - address,address - specify an address range 
+ - start~step - specify a starting line and a step. 
+                #QSE_SED_STARTSTEP enables this form.
 
 An @b address is a line number, a regular expression, or a dollar sign ($) 
 while a @b start and a @b step is a line number. 
 
 A regular expression for an address has the following form:
-- /rex/ - a regular expression @b rex is enclosed in slashes
-- \\CrexC - a regular expression @b rex is enclosed in @b \\C and @b C 
+ - /rex/ - a regular expression @b rex is enclosed in slashes
+ - \\CrexC - a regular expression @b rex is enclosed in @b \\C and @b C 
             where @b C can be any character.
 
 It treats the @b \\n sequence specially to match a newline character.
 
 Here are examples of line selectors:
-- 10 - match the 10th line
-- 10,20 - match lines from the 10th to the 20th.
-- /^[[:space:]]*$/ - match an empty line 
-- /^abc$/,/^def$/ - match all lines between @b abc and @b def inclusive
-- 10,$ - match the 10th line down to the last line.
-- 3~4 - match every 4th line from the 3rd line.
+ - 10 - match the 10th line
+ - 10,20 - match lines from the 10th to the 20th.
+ - /^[[:space:]]*$/ - match an empty line 
+ - /^abc$/,/^def$/ - match all lines between @b abc and @b def inclusive
+ - 10,$ - match the 10th line down to the last line.
+ - 3~4 - match every 4th line from the 3rd line.
 
 Note that an address range always selects the line matching the first address
 regardless of the second address; For example, 8,6 selects the 8th line.
