Can someone explain how to run Rational DOORS 9.6 in batch mode?

I tried doors -U -p -batch on command line where batchserver.dxl has following code: // batchserver.dxl IPC ipc = server 5093 string request / add functions for you interface here / while (true) { if (accept(ipc)) { if (!recv(ipc, request)) { warn "Server has disconnected" break } } else { warn "error accepting client connection" break }

 print "request: "
 print request
 print "\n"
 errors = false
 if (request == "shutdown_") {
     send(ipc, "done_")
     break
 }

 if (request == "errors_")
     break

 if (request == "quit_")
     continue

 ans = eval_ request
 if (ans == "errors in eval_ string") {
     print "errors in request\n"
 }

 send(ipc, ans)
 disconnect(ipc)

} But that gave me error: the syntax of the command is incorrect

I also tried doors -b dxl_programs\batchserver.dxl -p password-u username and that did not work. I got the error: 'doors' is not recognized as an internal or external command, operable program or batch file.

If someone could explain to me the command I need to run in a clear and thorough manner I would appreciate it.

Thanks
