Thanks Ben, I appreciate the feed back.
Here's another thought, I know PalmOS does not support 'calloc' but then why
is it included as a function in 'cstdlib' and all these include files are
listed under the MSL directory of CodeWarrior. It would seem to me that they
are indicating that if you do an #include that the function should then be
prototyped. Am I missing something here?

You are assuming that calloc() is a supported function on PalmOS. It is
not.
Here is a quick inline version that should work similar to the ANSI C
function calloc(), and will also show you how memory is allocated on PalmOS.
inline void *calloc(UInt16 num, UInt16 size)
{
void *memory = MemPtrNew(num * size);
if (memory)
{
MemSet(memory, num * size, 0);
}
return memory;
}
and this should match with
inline void free(void *memory)
{
if (memory)
{
MemPtrFree(memory);
}
}
since your code does deallocate memory, I'd assume.
