Question: Calling other programs from Maple

Hi,

I was wondering if anyone could tell me whether (and if so, how) it's possible to get Maple code to run an external program mid-process?  The program in question is qHull, which I downloaded from www.qhull.org.  Some searching has informed me it's possible to run C and JAVA bits in Maple, but with no programming experience I'm not sure whether that extends in any way to this, or if so, how.

The program, when downloaded, can be accessed through an MS-DOS interface, in which I would normally input a command line referencing a text file, with a couple of instructions, and getting a text file output.  I'm wondering if I can either get the Maple code to automatically launch the program and enter said command line, or just run the mathematics itself?

Thanks for any advice!
