To generate a document that shows the text "Hello world!":

%!PS
/Helvetica 20 selectfont
70 700 moveto
(Hello world!) show
showpage

If the viewer has a console, then there are the following ways to display the topmost element of the stack:

(Hello world!) ==

will display the <i>string</i> "(Hello world!)";

(Hello world!) =

will display the <i>content</i> of the string "(Hello world!)"; that is, "Hello world!";

(Hello world!) print

will do the same, without printing a newline. It may be necessary to provoke an error message to make the console pop up. The following program combines all four above variants:

%!PS
/Helvetica 20 selectfont
70 700 moveto
(Hello world!) dup dup dup
= print == % prints three times to the console
show % prints to document
1 0 div % provokes error message
showpage
