You need to update the cli_SetName field in the CLI structure associated with
your process.  To get this, do the following:


#include <exec/types.h>
#include <libraries/dosextens.h>

Process = (struct Process *)FindTask(0L);
CLI     = (struct CommandLineInterface *)BADDR(Process->pr_CLI);
cname   = (unsigned char *)BADDR(cli->cli_SetName);
if((len=strlen(cname)) > 254) len = 254;
cname[0] = len;
memcpy(cname, NewDirectoryName, len);

The 'BADDR' macro converts a BCPL address to a normal C address.  It's defined 
in some header file somewhere, probably as

#define BADDR(xxx) ((APTR)((LONG)xxx)<<2)

or some such thing.
