You are correct, that is what the doc say.
However, they lie, because when I run 
 -- Program 2
 #!/home/irv/euphoria/bin/exu
 object x
 x = system_exec("ls > DIRECTORY",0)

from an x-term, or from the command line, it runs just fine, and 
produces the output file 'DIRECTORY', which contains the names of the files as 
produced by ls.

Only when clicking on the program's icon does it hang.

Just to see if redirection could be part of the problem, I tried the 
following: 
 -- Program 3
 #!/home/irv/euphoria/bin/exu
 object x
 x = system_exec("mv FILEA FILEB",0)

This does not use redirection, but it also fails when run from the icon, and 
succeeds when run from an x-term.

Very puzzling.
