Has anyone ever had to save a COMT (csv) file to an NT box using ReportCaster... and force the file to read only?

I have had to do this in UNIX/LINUX and use the CHMOD command. On a Windows box, I'd use the DOS command ATTRIB to set the permissions:

ATTRIB [+R | -R] [+A | -A ] [+S | -S] [+H | -H] [drive:][path][filename]
       [/S [/D]]

  +   Sets an attribute.
  -   Clears an attribute.
  R   Read-only file attribute.
  A   Archive file attribute.
  S   System file attribute.
  H   Hidden file attribute.
  [drive:][path][filename]
      Specifies a file or files for attrib to process.
  /S  Processes matching files in the current folder
      and all subfolders.
  /D  Processes folders as well.
