How to remove names from a list in batch - windows

Question

I'm using windows bath, I have a list of names that I can add to but I don't know how to remove a name from the list.
So far my code is:
#echo off
setlocal enabledelayedexpansion
set allchoices=123456789
set "names=Bob,Steven,Harry"
set amount=6 ::max limit of list
set list=0
:start
::echoes a list of all names in the list
for /l %%i in (1; 1; %amount%) do (
call :sub %%i
)
goto check
:sub
for /f "tokens=%1 delims=," %%a in ("%names%") do (
echo %%i. %%a
set /a list=list+1
)
goto :eof
:check
::Remove a name from the list
choice /c !allchoices:~0,%list%! /m "What name do you want to remove?"
if errorlevel 3 (
for /f "tokens=3 delims=," %%a in ("%names%") do (
echo you have choosen to remove %%a
::remove third name in the list
goto start
)
)
if errorlevel 2 ::remove second name in the list
if errorlevel 1 ::remove first name in the list
I've tried using del but that turns out to delete a file in your folder.
I've tried renaming a specific name using set name[%%a]="" but that did nothing.
Any ideas?

Answer 1

Have a look at this example. There are many ways.
#echo off
setlocal enabledelayedexpansion
set names="Bob","Steven","Harry"
for %%i in (%names%) do (
set /a num+=1
set "!num!=%%~i"
)
for /l %%a in (1,1,%num%) do (
set choices=!choices!%%a
echo !num!.!%%a!
)
choice /c 123 /m "please select name to remove"
for /l %%a in (1,1,%num%) do if not "!%%a!"=="!%errorlevel%!" set new_names=!new_names! !%%~a!
echo %new_names:~1%
It can be done without the last for loop as well.. but I opted for it.

Answer 2

Here is some example code, for you to run, and then try to comprehend, I hope it helps rather than confuses:
#Echo Off
SetLocal EnableDelayedExpansion
For /F "Delims==" %%A In ('Set # 2^>NUL') Do Set "%%A="
Set "i=0"
For /F "Delims=:" %%A In ('FindStr "^::" "%~f0" 2^>NUL') Do (
Set /A i+=1
Set "#!i!=%%A"
Echo= !i!. %%A
)
:Ask
Set # 1>NUL 2>&1
If ErrorLevel 1 Echo= Empty names list&Timeout 3 1>NUL&Exit /B
Echo=&Set /P "Option= Choose a name to remove>"
Set #|Findstr "^#%Option%=" 1>NUL||GoTo :Ask
Set "Name=!#%Option%!"
Echo= You've chosen to remove "%Name%"
Timeout 2 1>NUL
Set "#%Option%="
ClS
For /F "Tokens=1*Delims=#=" %%A In ('Set # 2^>NUL') Do Echo= %%A. %%B
