What am i doing wrong using the Choice command with batch? - batch-file

Question

This is not the full code, since its about 1000 lines long, but here's the problem, when i come to this section of the game
choice /c abc1 /n
when i press "a" it's supposed to "medicalbag" and instead it acts like if i were to press "1" and goes back to start
when i press "b,c,1" they all go to "medicalbag".
i can't find a solution to this, i read about the command and apparently it supports these letters and numbers, when i change them out with just numbers they work just fine, but im really not sure what im doing wrong here.
:bag
cls
echo *****************************
echo a) Medical supplies
echo b) Consumables
echo c) Weaponry
echo -----------------------------
echo 1) back
echo -----------------------------
choice /c abc1 /n
if %errorlevel% == a goto medicalbag
if %errorlevel% == b goto consumablebag
if %errorlevel% == c goto weaponrybag
if %errorlevel% == 1 goto start
:medicalbag
cls
echo *****************************
echo Bandages: %bandagecount%
echo -----------------------------
echo 1) back
echo -----------------------------
choice /c 1 /n
if %errorlevel% == 1 goto bag
:consumablebag
cls
echo *****************************
echo Canned food: %cannedfoodcount%
echo Purified water: %purifiedwatercount%
echo Dirty water: %dirtywatercount%
echo -----------------------------
echo 1) back
echo -----------------------------
choice /c 1 /n
if %errorlevel% == 1 goto bag
:weaponrybag
cls
echo *****************************
echo a) combatknife: %combatknifecount%
echo -----------------------------
echo 1) back
echo -----------------------------
choice /c a1 /n
if %errorlevel% == a goto combatknifecheck
if %errorlevel% == 1 goto bag

Answer 1

the errorlevel of the choice keys defined using the /c switch is returned according to the keys position in the list.
with /c abc1:
keypress: errorlevels reuturned:
a 1
b 2
c 3
1 4
To get the literal keypress, you need to use a for /f loop to capture the keypress:
For /f "delims=" %%G in ('choice /n /c abc1')Do Echo(You pressed: %%G
Note - the /n switch MUST be used when using a for loop to capture the pressed key.

Here is an example of a dynamic menu system that will return the user selected value and the description of that value.
#echo off
setlocal EnableDelayedExpansion
CALL :MENU "Medical supplies" "Consumables" "Weaponry" "Back"
CALL :CHOSE
pause
goto :eof
REM ONLY FUNCTIONS BELOW HERE
:MENU
set /a "OptionNo=0"
set "choices="
FOR %%I IN (%*) do (
set /a OptionNo+=1
call :ResolveChar !OptionNo!
set "Option!retval!=%%~I"
set "choices=!choices!!retval!"
echo [!retval!] %%~I
)
GOTO :EOF
:ResolveChar
SETLOCAL
set "keys=_ABCDEFGHIJKLMNOPQRSTUVWXYZ"
set "_startchar=%1"
CALL SET "char=%%keys:~%_startchar%,1%%"
ENDLOCAL & SET "retval=%char%"
goto :eof
:CHOSE
choice /c !choices! /cs /m "Select Your Option: " /n
call :ResolveChar %errorlevel%
set "Option=!Option%retval%!"
echo You Selected: %retval% - %Option%
GOTO :EOF
