NAME
        FindName -- find a system list node with a given name

   SYNOPSIS
        node = FindName(start, name)
        D0,Z            A0     A1

        struct node *findname(struct list *, strptr);

   FUNCTION
        Traverse a system list until a node with the given name is found.
        To find multiple occurrences of a string, this function may be
        called with a node starting point.

        No arbitration is done for access to the list!  If multiple tasks
        access the same list, an arbitration mechanism such as
        SignalSemaphores must be used.

   INPUTS
        start - a list header or a list node to start the search
                (if node, this one is skipped)
        name - a pointer to a name string terminated with NULL

   RESULTS
        node - a pointer to the node with the same name else
            zero to indicate that the string was not found.
