This paper presents the properties and behaviour of solutions to a class of n-dimensional functional differential systems of neutral type. Sufficient conditions for solutions to be either oscillatory, or limπ‘‘β†’βˆžπ‘¦π‘–(t) = 0, or limπ‘‘β†’βˆž|𝑦𝑖(t)|=∞, 𝑖=1,2,…,𝑛, are established. One example is given.
