On the ZX Spectrum, standard error is on stream 1:

 

 

=={{header|Batch File}}==

The redirection operator <code>1>&2</code> causes all output on stream 1 (standard out) to be redirected to stream 2 (standard error).

The redirection can be moved to the end of the line, too.

=={{header|Metafont}}==

Metafont has no a real way to send a text to the standard output/error nor to a file. Anyway it exists the <code>errmessage</code> command which will output an error message and prompt the user for action (suspending the interpretation of the source).

we can also use the ''out_channel'' '''stderr''':

=={{header|ooRexx}}==

ooRexx provides a .error object that writes output to the standard error stream.

The .error object is a proxy that delegates to a backing stream, so this might be redirected.

By default, this delegates to the .stderr object, which can also be used directly.

or in 'Classic REXX style'

=={{header|PowerShell}}==

standard Write-Error cmdlet is mainly for sending annotated error messages

to the host:

Note that this outputs more than just the message,

because behind the scenes it is an uncaught exception:

+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException</pre>

To accurately reproduce the behavior of other languages one has to resort to .NET in this case:

 

=={{header|PureBasic}}==

Standard error output can be used in conjunction with [http://www.purebasic.com/documentation/process/readprogramerror.html ReadProgramError()] to reads a line from an other programs error output (stderr).

 

 

=={{header|Python}}==

{{works with|Python|2.x}}

 

 

{{works with|Python|3.x}}

 

 

Works with either:

 

 

=={{header|R}}==

**Prints "Goodbye, World!" to standard error**

 

print to Console.error made !, "Goodbye, World!"

 

=={{header|Racket}}==

=={{header|Retro}}==

 

=={{header|REXX}}==

<br>If the &nbsp; '''stderr''' &nbsp; name is supported and enabled, the output is written to the terminal.

<br>If not supported or disabled, the output is written to a (disk) file named &nbsp; '''STDERR'''.

 

===version 2===

Same as above, but uses a different style and also invokes &nbsp; '''charout''' &nbsp; instead of &nbsp; '''lineout'''.

 

===version 3===

* 07.07.2014 Walter Pachl

* enter the appropriate command shown in a command prompt.

Call lineout ,'Hello, world!'

Say 'and this is the error output:'

 

=={{header|Ring}}==

 

=={{header|Ruby}}==

The following also works, unless you have disabled warnings (ruby command line option "-W0" or set <code>$VERBOSE=nil</code>)

 

=={{header|Run BASIC}}==

window.open('','error_msg','');

document.write('Goodbye, World!');

Run Basic runs in a browser.

writeln!(stderr, "{}, {}!", goodbye, world).expect(errmsg);

or

use std::io::{self, Write};

 

io::stderr().write(&*format!("{}, {}!", goodbye, world).as_bytes()).expect("Could not write to stderr");

// Clearly, if you want formatted strings there's no reason not to just use writeln!

This is a call to the Java run-time library. '''Not recommendated'''.
