oplrun command does not work

Does anyone know why my "oplrun command" does not run my cplex model?

I wrote two following lines in matlab and expected it to run my cplex model. But it only opens IBM ILGO CPLEX without runing the model.

command = 'oplrun model.mod model.dat';
[status, cmdout] = system(commandx); 

Any help is greatly appreciated.

Thanks.

Could you confirm that model.mod and model.dat are in the current directory at the time you system() ?

And could you confirm that oplrun is in your Windows path ?

Thank you so much @Walter Roberson. Directory was the problem.
