+{\tt output} and {\tt errors} are array references.}
+
Executes another program in Unix or Windows.
The first form takes a command string, such as {\tt "emacs file.txt"}.
The semantics of the third and fourth versions is different from the first two
and is described in more details below.
-If {\it sync} is FALSE (the default), flow of control immediately returns.
-If TRUE, the current application waits until the other program has terminated.
+If {\it flags} parameter contains {\tt wxEXEC\_ASYNC} flag (the default), flow
+of control immediately returns. If it contains {\tt wxEXEC\_SYNC}, the current
+application waits until the other program has terminated.
In the case of synchronous execution, the return value is the exit code of
the process (which terminates by the moment the function returns) and will be
terminated successfully. Also, while waiting for the process to
terminate, wxExecute will call \helpref{wxYield}{wxyield}. The caller
should ensure that this can cause no recursion, in the simplest case by
-calling \helpref{wxEnableTopLevelWindows(FALSE)}{wxenabletoplevelwindows}.
+calling \helpref{wxEnableTopLevelWindows(false)}{wxenabletoplevelwindows}.
For asynchronous execution, however, the return value is the process id and
zero value indicates that the command could not be executed. As an added
-complication, the return value of $-1$ in this case indicattes that we didn't
+complication, the return value of $-1$ in this case indicates that we didn't
launch a new process, but connected to the running one (this can only happen in
case of using DDE under Windows for command execution). In particular, in this,
and only this, case the calling code will not get the notification about
process termination.
-If callback isn't NULL and if execution is asynchronous (note that callback
-parameter can not be non-NULL for synchronous execution),
+If callback isn't NULL and if execution is asynchronous,
\helpref{wxProcess::OnTerminate}{wxprocessonterminate} will be called when
-the process finishes.
+the process finishes. Specifying this parameter also allows you to redirect the
+standard input and/or output of the process being launched by calling
+\helpref{Redirect}{wxprocessredirect}. If the child process IO is redirected,
+under Windows the process window is not shown by default (this avoids having to
+flush an unnecessary console for the processes which don't create any windows
+anyhow) but a {\tt wxEXEC\_NOHIDE} flag can be used to prevent this from
+happening, i.e. with this flag the child process window will be shown normally.
+
+Under Unix the flag {\tt wxEXEC\_MAKE\_GROUP\_LEADER} may be used to ensure
+that the new process is a group leader (this will create a new session if
+needed). Calling \helpref{wxKill}{wxkill} with the argument of -pid where pid
+is the process ID of the new process will kill this process as well as all of
+its children (except those which have started their own session).
Finally, you may use the third overloaded version of this function to execute
a process (always synchronously) and capture its output in the array
{\it output}. The fourth version adds the possibility to additionally capture
the messages from standard error output in the {\it errors} array.

+\func{wxChar}{wxT}{\param{char }{ch}}

+\func{const wxChar *}{wxT}{\param{const char *}{s}}
+
+wxT() is a macro which can be used with character and string literals (in other
+words, {\tt 'x'} or {\tt "foo"}) to automatically convert them to Unicode in
+Unicode build configuration. Please see the
+\helpref{Unicode overview}{unicode} for more information.
+
+This macro is simply returns the value passed to it without changes in ASCII
+build. In fact, its definition is:
+\begin{verbatim}
+#ifdef UNICODE
+#define wxT(x) L ## x
+#else // !Unicode
+#define wxT(x) x
+#endif
+\end{verbatim}
+
+\membersection{wxTRANSLATE}\label{wxtranslate}
+
+\func{const wxChar *}{wxTRANSLATE}{\param{const char *}{s}}
+
+This macro doesn't do anything in the program code -- it simply expands to the
+value of its argument (expand in Unicode build where it is equivalent to
+\helpref{wxT}{wxt} which makes it unnecessary to use both wxTRANSLATE and wxT
+with the same string which would be really unreadable).
+
+However it does have a purpose and it is to mark the literal strings for the
+extraction into the message catalog created by {\tt xgettext} program. Usually
+this is achieved using \helpref{\_()}{underscore} but that macro not only marks
+the string for extraction but also expands into
+\helpref{wxGetTranslation}{wxgettranslation} function call which means that it
+cannot be used in some situations, notably for the static arrays
+initialization.
+
+Here is an example which should make it more clear: suppose that you have a
+static array of strings containing the weekday names and which have to be
+translated (note that it is a bad example, really, as
+\helpref{wxDateTime}{wxdatetime} already can be used to get the localized week
+day names already). If you write
+\begin{verbatim}
+static const wxChar * const weekdays[] = { _("Mon"), ..., _("Sun") };
+...
+// use weekdays[n] as usual
+\end{verbatim}
+the code wouldn't compile because the function calls are forbidden in the array
+initializer. So instead you should do
+\begin{verbatim}
+static const wxChar * const weekdays[] = { wxTRANSLATE("Mon"), ..., wxTRANSLATE("Sun") };
+...
+// use wxGetTranslation(weekdays[n])
+\end{verbatim}
+here.
+
+Note that although the code {\bf would} compile if you simply omit
+wxTRANSLATE() in the above, it wouldn't work as expected because there would be
+no translations for the weekday names in the program message catalog and
+wxGetTranslation wouldn't find them.

+\membersection{\_}\label{underscore}
+
+\func{const wxChar *}{\_}{\param{const char *}{s}}
+
+This macro expands into a call to \helpref{wxGetTranslation}{wxgettranslation}
+function, so it marks the message for the extraction by {\tt xgettext} just as
+\helpref{wxTRANSLATE}{wxtranslate} does, but also returns the translation of
+the string for the current locale during execution.

+(in other words, in the debug build) but disappear completely in the release
+build. On the other hand, the wxCHECK macros stay event in release builds but a
