In this task, the job is to create a new empty file called "output.txt" of size 0 bytes
and an empty directory called "docs". This should be done twice: once "here", i.e. in the current working directory and once in the filesystem root.

for Dir in ["/" "./"] do
   File = {New Open.file init(name:Dir#"output.txt" flags:[create])}
in
   {File close}
   {OS.mkDir Dir#"docs" ['S_IRUSR' 'S_IWUSR' 'S_IXUSR' 'S_IXGRP']} 
end
