Unable to modfiy an existing file

[Saravanan Manickanainar Dakshinamoorthy]

Hi,

      Machine : SunOS 5.8 sparc SUNW,Sun-Blade-100
     emacs version : 21.3

      I am not able to modify an existing file which has write 
permission, but the
directory under which the file present has only read and execute permission.
I can modify that with vi editor.

      eg
           foo-dir <directory>   permisssion   r-xr-xr-x
                |
                foo <file>    permission rw-rw-rw-

Thanks,
saravanan
