The run-time system does not recognize as valid the command line format you have specified.
Alternatively, the generic command-line interpreter, which must be present if your program is to be run successfully, is not found on your system.
Alternatively, you have set an invalid COBSW value.
Rerun your application with a valid command line.
Make sure that the interpreter is present to enable your system to pick up the commands correctly and then rerun your program.
Reset COBSW to a valid value.
