Arrow keys

[Zai1208]

I figured out an easy way to do arrow key detection in batch

Code: Select all

choice /cs /n /c HKPM
:: H is the up arrow
:: K is the left arrow
:: P is the down arrow
:: M is the right arrow

This actually works

Edit:
Whoops I made a mistake I guess ¯\_(ツ)_/¯

I have never seen any version of choice that supports an /S option, certainly not in any standard Windows CHOICE command.

Not surprisingly, this does not work on my Windows 10 machine.

You must have a non-standard CHOICE.EXE file.

I agree with Dave, also doesn't work for me. Where did you find this choice.exe that a) works without spaces between the options and b) supports an option /s?

It looks like it might be the DOS or NT Resource Kit version, where /S is used instead of /CS.

I got it from here: http://manmrk.net/tutorials/DOS/msdos62 ... OICE_E.HTM

At the bottom of that page it shows how to use batch + DEBUG to patch the old version of CHOICE to get the non-standard behavior that can read special keys.

Not very useful, considering most installations of Windows do not support the DEBUG command. Also, there are multiple versions of CHOICE out there, and I'm sure that patch only works with a very specific version.
