The Remember structure is defined in <intuition/intuition> as follows:

    struct Remember
        {
        struct Remember *NextRemember;
        ULONG RememberSize;
        UBYTE *Memory;
        };

Generally, the Remember structure is handled only by the system.  Here are
its fields:

    NextRemember - The link to the next Remember structure.
    RememberSize - The size of the memory tracked by this node.
    Memory       - A pointer to the memory tracked by this node.
