HELP!!!  The following Think C code is my attempt at registering a name
on AppleTalk.  This either blows up or registers garbage.  I'm new to the MAC
and I was wondering if someone could point out where I'm blowing it.

Thanks in advance.

	Ptr			nbpNamePtr;

	errCode = MPPOpen();
	if ( errCode != noErr)

	}

	/* Call memory manager to allocate ABusRecord */
	myABRecHandle = (ABRecHandle)  NewHandle(nbpSize);

	}
