Editing Smalltalk (section)

==Hello World example==
The [[Hello world program]] is used by virtually all texts to new programming languages as the first program learned to show the most basic syntax and environment of the language. For Smalltalk, the program is extremely simple to write. The following code, the message "show:" is sent to the object "Transcript" with the String literal 'Hello, world!' as its argument. Invocation of the "show:" method causes the characters of its argument (the String literal 'Hello, world!') to be displayed in the transcript ("terminal") window.
<syntaxhighlight lang="smalltalk">
Transcript show: 'Hello, world!'.
</syntaxhighlight>
To see the results of this example, a Transcript window must be open.
