Other than doing magic to open a display window etc - which ought to be possible but I’ve never looked at it - the simplest thing is to use the stdio stream. As in

FileStream stdio nextPutAll: ‘Hello, World’; flush.

That should be

    FileStream stdout nextPutAll: ‘Hello, World’; cr; flush.
 
or

    FileStream stderr nextPutAll: ‘Hello, World’; cr; flush.


Your words of deathless prose should appear in whatever place stdout would appear, typically the terminal window from which you fired up Squeak. I have to admit I have no idea where that might be if you started Squeak from some login or startup script. Maybe it would require some added > mylogfile magic?

It is easier to change the specification to fit the program than vice versa.
