Indicates whether or not the command ran successfully. Zero indicates the command could not be run or was aborted; any other number indicates the command was run for at least some files. (Note that this is not the "exit code" for external commands. For external commands it only indicates whether or not Opus launched the command. If you need the exit code of an external command, use the WScript.Shell Run or Exec methods to run the command.)
