Getting an output from a program

Question

I need to run a program on a robot using os.execute or similar and then collect a return value (a slot number).  I've tried the 'return' keyword but the program just spits out the normal "true" saying the program ran, but nothing else.

The code I have now is:

#component declarations and requires statements for robot and inventory controller

lookingFor = args[1]

for i=1,robot.inventorySize()do
	robot.select(i)
	item = invcon.getStackInInternalSlot()
	if item ~= nil then
		itemName = item['label']
	end
	if lookingFor == itemName then
		return i
	end
end
return 0



Anyone know if this is possible, and if so how to do it?
