Do you mean that one way would be how you displayed the text for the 
console/terminal using cout << ? That much I do know but thank you for being 
clear!

At the first glance it looks quite compilated. My current solution is like 
this:

const char * BibleObject::getVerse(const char *keyStr)
{
	ListKey result;
	VerseKey parserKey;

	result = parserKey.ParseVerseList(keyStr, parserKey, true);
	result.Persist(true);

	mBible->SetKey(result);

	char* returnBuffer = Con::getReturnBuffer(2024);
	*returnBuffer = 0;
U32 numCharsInBuffer = 0;

	for(*mBible = TOP; !mBible->Error(); (*mBible)++) {
		const char *ns = mBible->StripText();
		U32 strLength = dStrlen(ns);
		if(numCharsInBuffer + strLength >= 2024) {
			// Verse string was too long and was truncated
			break;
		}

		dStrcat(returnBuffer,ns);
		numCharsInBuffer += strLength;

	}

	return returnBuffer;
}


As you can see the result's length is limited. But of course I could and 
should use something like std::string and return that but I just wanted to 
make this in the right way.

It sure does! Thanks.

It's alright if I can't get a perfect solution for this now that I do have a 
code that works.




May God bless you too Troy.
