Umm, below is the code I posted that you responded to. It already
doesn't have a star where you indicated so that doesn't seem to
be the problem. :(
BOOL MakeArray (mystruct ***array, LONG arraysize)
{
if (**array = (mystruct ***) AllocVec ( arraysize * sizeof (mystruct
*)))
{
for (i = 0; i < arraysize; i++)
{
if ( ! *((array[i]) = (mystruct *) AllocVec (sizeof (mystruct)))
break;
