Ok, I tried the following but it doesn't work. I am assuming I am
not addressing the variables in the correct way within the funtion.
Here's what I am doing:

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;
