Workflow FileList Deployment

iwcnb

I have a workflow that called an external task (.ipl file) to deploy a File List. The .ipl file contains the following code to deploy the filelist but it does not seem to work. Am I using the correct syntax to call the deployment. Is the syntax wrong?
---------------------------------
open COMMAND, 'c:/iw-home/opendeploy/OpenDeployNG/bin/iwodstart FilelistDeploymentName |';
close COMMAND;
