Passing parameters

Is it possible to pass paremeters to Torque functions as in regular C++ like so

loadMyMission(1);

so that when main.cs loadMyMission() starts, I could do something like this!

switch (parmeter)
{
case 1
exec (...\mission1.mis)
case 2
exec (...\mission2.mis)
case 3
exec (...\mission3.mis)
default
exec (...\mission0.mis)
}
