Hi Richard,

If you re-read the entry for 'open file' in the
Transcript DIctionary, you'll see a paragraph that
says: "If you don't specify a form, the file is opened
for update."
As you can't open a locked file for update, the file
can't be opened. Why your sandox-program claims you're
messing in the regitry, is a mistery to me, however.

Hope this helped,

Jan Schenkel.
