George, How HUGE is your global structure? You should never create nor reference globals from within the PalmMain function. You should also keep your use of globals to a minimum. But any globals you do use in your app can be created/initialized in your AppStart() function.
MemPtrNew allocates non-movable memory, I believe you can do it like so: UInt32 *myVar myVar = (*UInt32) MemPtrNew(sizeof(UInt32)); // allocates a UInt32 on the dynamic heap *myVar = 1; // set its value //free the memory MemPtrFree(myVar); // note, because this is non moval memory, you should not keep it around long... if you need to keep something around, try using MemHandleNew, MemHandleLock and MemHandleFree. Its all in the palm OS reference guide. "George" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hello, > > Since I'm a Palm OS newbie, I need some help.
