Running an external program from within BlitzMax

So I have an app that needs to print some pdf's and I was hoping to do that simply by running lpr from my app. I don't seem to see a system() or exec() function, is there something I am missing?

Try System_ (it's declared in pub.mod/stdc.mod/stdc.bmx).

Or OpenURL() if you don't want program execution to stop until the process finishes...
