That's awesome! I'm surprised by your discovery, and as a programming lover, I also have serveral questions about it.
1, Why do the calculator "execute" the code inputed in the buffer? I mean, I totally have no idea about the reason why the buffer overflow affects the normal execution of the original program.
2, According to the conversations above, I've got that the maximum code length is around 3KB. However, as I know, the size of the overflow buffer is around 90B, which is far less than 3KB. How to input the binary code whose size is more than that of the overflow buffer? Or is there any way to change the start address of the overflow buffer?
I would appreciate it if you give answers to these questions, thank you.

@user202729 sorry to disturb you
could you pls tell me how to program it?I want to program it manually or use another calculator to

@user202729 I've just found that the ES series can enter the basic overflow(LineIO),sobdo you have the ES ROM?Can them be programmed?
