If you want to send it, you must have an address. I did it.

A set of 8-bit signed numbers are stored in 30h-35h cells of on-chip RAM, and the numbers of cells greater than 0, less than 0 and equal to 0 are counted, and the results are stored in 20H, 2 1H and 22H cells off-chip respectively.

You can use it if you change it. If you can change it, you won't ask me again.
