Recursion Logic

[joeyvitoro]

Hi, I'm writing a script in a proprietary language that is very similar to Java and I have a question about the best logical approach. The script...

string getTargets(Object obj, string finalString)
{
	Link lnk
	for lnk in obj -> "*" do
	{
		Object newObj = target(lnk)
		finalString = getTargets(newObj,finalString)
	}

	Module newMod = module(obj)
	string returnString = obj."Absolute Number"
	returnString = newMod."Prefix" returnString "\n" finalString

	return returnString 
}

Module mod = current
Object obj
for obj in mod do
{
	print getTargets(obj, "")
}

Each module contains a number of objects, and each object can contain links to other objects. My task is to print all of the lowest level objects. This script does just that, but I need to know what level they are at. (Level 1, level 2, level 3, etc). So this script might print out:
AAA-1
AAA-2
BBB-1
AAA-3
AAA-4
BBB-1
CCC-1
BBB-2
CCC-2

How can I, for example, make it print out:
AAA-1
AAA-2
...BBB-1
AAA-3
AAA-4
...BBB-1
......CCC-1
...BBB-2
......CCC-2

I've added a counter to keep track of how many times I enter and exit the function. It works, but please let me know if there is a better way.

string getTargets(Object obj, string finalString, int count)
{
	count++
	Link lnk
	for lnk in obj -> "*" do
	{
		Object newObj = target(lnk)
		finalString = getTargets(newObj, finalString, count)
	}
	count--

	Module newMod = module(obj)
	string returnString = obj."Absolute Number" ""
	returnString = newMod."Prefix" returnString "\n" finalString
	returnString = "--" count "--" returnString 
	return returnString 
}
