This is how I understand it:
1.As for keyboard input, choice is ultimately implemented with the two basic functions ah=0 and ah=1
2.No matter how good choice is, not every system has it preinstalled (my XP doesn't)
3.No matter how powerful choice is, its functions are fixed, while if p has these two basic functions, everything else can be left to everyone's imagination. Which is better, fish or a fishing rod, everyone understands
4.Making a farewell to choice our goal, let everyone work on it together

This way you don't need so many jumps
...
ping -n 2 127.1>nul
if %n% LEQ 5 goto loop
echo.
echo Time's up, run automatically!
pause

“Everyone understands whether fish is better or the fishing rod is better”
I believe there are only a few who really understand
After all, compared with fish
a fishing rod still needs a pool of water and some bait
If you really want to say the fishing rod is better
then ask which is better, a fishing rod or a stick + line + hook?
And which is better, fish or braised carp?
How should one choose then
Don't forget that debug is a very troublesome thing in cmd
Using it will bring many potential problems (not just code pages)

What the poster on the 35th floor said makes sense, but:
"Don't forget that debug is a very troublesome thing in cmd

I really don't know about that. Could you tell me a thing or two? If it's fatal then I'll give up this idea. Since debug makes it feasible to embed small assembly in p, I think it's quite important.

For the general situation, you can refer to the following threads
http://www.cn-dos.net/forum/viewthread.php?tid=9452
http://www.cn-dos.net/forum/viewthread.php?tid=20682
What is currently known is
using Debug inevitably requires enabling ntvdm
and that is a command-line environment very different from cmd
for example command-line auto-completion
for example long and short filenames

There's another problem: this choice cannot pause and wait for input (maybe this is what brother qzwqzw in the post above meant by "command-line auto-completion"), but instead keeps looping inside the :loop label.

The issue on the 37th floor is being checked...
The issue on the 38th floor should not exist. Could it be that it was run without parameters? Which post's program was it?

I didn't read carefully. Turns out the 27th floor already has the parameter-based pause function.
There's another problem (environment XP SP3)
During dynamic detection, if certain keys are pressed (such as Ctrl), it will then pseudo-hang, meaning pressing anything afterward gets no response.
Pressing several letters quickly can also cause the above situation.
Not sure whether this also happens when run with parameters?

The "pseudo-hang" phenomenon does happen, still looking for the cause...
But it should be unrelated to debug, inc.com does it too.

Wrote a piece of code that can return ascii:

i
echo %errorlevel%

All experts here. I can't understand it, so I'll save it for future use.
