Editing PostScript (section)

=== "Hello world" ===
A [[Hello World program]], the customary way to show a small example of a complete program in a given language, might look like this in PostScript (level 2):

<syntaxhighlight lang="postscript">
 %!PS
 /Courier             % name the desired font
 20 selectfont        % choose the size in points and establish 
                      % the font as the current one
 72 500 moveto        % position the current point at 
                      % coordinates 72, 500 (the origin is at the 
                      % lower-left corner of the page)
 (Hello world!) show  % paint the text in parentheses
 showpage             % print all on the page
</syntaxhighlight>

or if the output device has a console

<syntaxhighlight lang="postscript">
 %!PS
 (Hello world!) =
</syntaxhighlight>
