 First of all, thanks for actually finding out what to do and where;
having the current directory in the title bar is really nice. However,
there's a better way to find the address of the CON:/RAW: window the
shell is running in; documented very scantily in the AmigaDOS manuals
is the fact that if you send a DiskInfo packet to your console
handler, the id_VolumeNode field in the InfoData structure holds the
desired window address (this has also been mentioned on the net a
couple of times). So here's the needed code to do it in the proper
way.

[This goes in main.c, just before init()]

#include	<intuition/intuition.h>
#include	<libraries/dosextens.h>
#include	<libraries/dos.h>
extern struct Library	*OpenLibrary();
struct Library	*IntuitionBase;
struct Window	*wb_window;

[This goes where Hobie's code did, right at the end of init()]

   wb_window = NULL;
#if	RAW_CONSOLE
   if ((IntuitionBase = OpenLibrary("intuition.library", 0L)) != NULL) {
	BPTR			iLock;
	struct FileHandle	*conF;
	struct InfoData		*infTemp;
	extern long		dos_packet();

	iLock = (BPTR) Input();
	conF = (struct FileHandle *) BADDR(iLock);
	infTemp = (struct InfoData *) malloc(sizeof(struct InfoData));
	if (infTemp == 0)
		return;
	/*
	 * Send the packet.
	*/
	if (!dos_packet(conF->fh_Type, ACTION_DISK_INFO, 
			((ULONG) infTemp) >> 2)) {
		free((void *) infTemp);
		return;
	}
	wb_window = (struct Window *) infTemp->id_VolumeNode;
   }
#endif

 Hobie's other code stays the same, and works fine.

 People who wish to be thorough should probably check to make sure
that Input() is interactive; I didn't bother because I was feeling
lazy when I wrote the code.
