My program has a MenuFrame with  with MenuItems in it. If I click on
"New", I would like to open the Filedialog box. I am a beginner and
experimenting with some basic programs. I get an error <identifier>
expected, on the line where I have specified
" f.setVisible(true); "
Can some one please provide any insight into this. I have looked into
this program a number of times and I am unable to rectify this error.

Thanks in advance.
Nicky.
