You don't show your code, but I'm guessing you're using the system LIST form - you could try catenating the arguments into a single string and passing that to system e.g. instead of system $arg1, $arg2, $arg3;, try either system $arg1 . $arg2 . $arg3;, or system "$arg1 $arg2 $arg3";.
A user level that continues to overstate my experience :-))
