RUN COMMAND /C COPY MyFile.TXT YourFile.TXTExternal DOS executables should be startable with the RUN command without the /N switch in use; you may need to create a .PIF file for the DOS executable if it has unusual memory or screen behaviors (right click in the DOS executable under Windows Explorer, select Properties, and adjust the PIF settings as needed.) Alternatives to the run command exist; the WSH Wscript.Shell object and Shell.Application object provide mechanisms to run executables or documents associated with executables; the ShellExecute() API (and the _ShellExecute class in _environ.vcx in the FFC) will run DOS executables, and my API_APPRUN class (available in the Files section for download) will all launch DOS executables.
