GotoWhen the batch file runs here, it will jump to the label specified by Goto, which is generally used with if. For example:
Goto end
: End
Echo this is the end
The label is represented by a string. The row where the label is located is not executed.

Jump instruction is used to implement the program flow jump, in the ARM program there are two ways to achieve the program flow jump:1) Use specialized jump commands.2) write the jump address value directly to the program counter PC.
By writing the jump address value to the program counter PC, you can achieve any jump in the 4GB address space, and use it together before jumping

such as instructions, you can save the future return addr
The router's three-layer forwarding relies primarily on the CPU, while the three-layer forwarding of the three-layer switch relies on the ASIC chip, which determines the significant difference in forwarding performance. Of course, the three-layer switch does not completely replace the router, the router has a rich interface type, good traffic service level control, strong road capacity and so on is still the weak link of the three layer switch. The current three-layer switch typically uses VLANs
When information needs to be transferred between two networks, the interconnection device of common routers is responsible for the transmission of data. The main work of the router is: The decision of the path and the forwarding of the packet (from the router an interface input, and then select the appropriate interface output); Maintenance path by the table.The way the router works is very concise, extracting the destination address from the receivin

Therefore, it does not support each of the possible message delivery options in each messaging system.
