If I start a exu program running from the command line or clicking on
it's icon, how do I get a terminal window to open so I can puts() to
that window.

Chris:

   I have developed code that allows a Euphoria user to write
   and use X-Windows, XT (Intrinsic Toolkit, Xaw & Xaw-3d Athena Widgets,
   and Motif Widgets.
   I am writing a pure X-Window demo that has some buttons to execute
   system calls like system("date",2) which send date text to the console.
   The text appears when I run in terminal mode because of course the the
   terminal is already open.
   If the demo is started from the run command the text goes to the
   hidden console like you say. What concerns me is a less knowledgable
   user will think the demo doesn't work. So I was trying to find a way
   to make the console visible when the program is run without depending
   on the users knowledge. I can open a xterm terminal but I don't
   know how to change it be used as standard out.

Thanks Chris and Guillermo !

  What I finally did was:
 

system(" xterm -C +sb -title \"MOTOR'S X-WINDOW DEMO\" &", 2)
  system(" date >/dev/console",2)
