// Hack: There's no room in the EXCEPINFO for a filename and line number. This is a problem when scripts
// call each other because the filename/line need to percolate with the error so that the eventual
// error message displays the filename/line of the script where the error orgiginated.
// We'll just pack the error in with the description and then unpack it when the IDirectMusicScript
// interface returns its DMUS_SCRIPT_ERRORINFO, which does have a filename.
