Implement LDC_W_ARRAY, in Mic-1. The command has a 2-byte offset to the first constant to load onto the stack. The third byte after the opcode is the count of how many constants to push. If the constant is zero, then nothing should be pushed. Be very careful when you create label names. It is safest to always create a new label, than to reuse an existing label from the microcode.
