Dear Robert,
I can reproduce the problem on my machine.
There seems to be a problem with the example or with the File.ozf
implementation.
There are two different ways to open a file in Oz:
{New Open.file init(url:URL)}
and
{New Open.file init(name:NAME)}
The function File.readList of the example uses the first form. But
"stdin" is not a valid URL. It is a valid filename, however.
If you replace the line
L = {File.readList stdin}
with
F = {New Open.file init(name:stdin)}
L = {F read(list:$ size:all)}
{F close}
the example should work as expected.
Cheers,
Wolfgang

Hi,
I'm a newbie in Oz and currently working with CTM (3rd printing)
When I try to execute the standalone program wordapp.oz (pp 225-230),
I've got this error message:
***error in URL support
***
*** Cannot locate file
*** File name: stdin
*** Operation: open
***
*** Call stack:
*** procedure 'get' in file
"f:cygwin/home/Administrator/Mozart-1-3-2/mozart/share/lib/init/Resolve.oz",
line 394, column 6, PC = 24427592
**
The only change I've made in the code shown on page 227 is the
following: instead of File in the import part, I had to write File at
<location of File.ozf> on my computer.
On my computer, Mozart is running on Windows Vista Edition familiale
Premium
I can't figure out where the problem comes from.
Is it a problem with Vista? with cygwin? with the funcor File?
Thanks for any help
Cheers
Robert
