Batch Coding Menu Option to Go Back - batch-file

Question

I'm fairly new to coding, and I've been told to start with batch files. I'm attempting to make a text based game that prompts the user to choose between a few options to progress through the story. I've got the basic idea down, but I ran into some trouble with making a menu. I've done some research on here, and have searched other sites, but can't seem to make heads or tails of some of the answers to similar questions. Most of the answers write out code that I assume would work, but I need to know the WHY behind these answers, and I haven't really found any answers that I could understand.
TLDR; I need to make a menu for a text based game, that allows the user to return the label they left off on.
What I have so far:
:MainMenu
cls
echo Input Options:
echo.
echo ::1) View Storyline Changes
echo ::2) Restart Test
echo ::3) Resume Test
echo ::4) Help
echo ::5) Quit
echo.
set /p input=Input:
if "%input%" == "1" goto StorylineChanges
if "%input%" == "2" goto Rst
if "%input%" == "3" goto ResumeTest
if "%input%" == "4" goto HelpScrn
if "%input%" == "5" exit
:StorylineChanges
cls
echo Unimportant to test.
echo.
echo Input "m" to go back
echo.
set /p input=Input:
if "%input%" == "m" goto Main Menu
if "%input%" == " " goto WrongInputStorylineChanges
:Rst
cls
goto :StartTest
echo off
:ResumeTest
cls
REM ***THIS IS WHERE I NEED HELP ***
pause >nul
goto StartTest
As you can probably immediately tell, I BARELY have a grasp on basic commands, so please keep that in mind if you provide an answer. I'd really appreciate any help you guys could give me. Thanks so much.

Answer 1

I cannot unravel the spaghetti code, but I can give an example
detailing how to go back to the menu as the title asks.
#echo off
:MainMenu
cls
echo Input Options:
echo.
echo ::1) View Storyline Changes
echo ::2) Restart Test
echo ::3) Resume Test
echo ::4) Help
echo ::5) Quit
echo.
set /p input=Input:
if "%input%" == "1" call :StorylineChanges
if "%input%" == "2" call :Rst
if "%input%" == "3" call :ResumeTest
if "%input%" == "4" call :HelpScrn
if "%input%" == "5" exit /b 0
goto :MainMenu
:StorylineChanges
echo Use "goto :eof" to exit script or exit called label.
pause
goto :eof
:Rst
echo Use "exit /b" to exit script or exit called label with a errorlevel.
pause
exit /b 0
:ResumeTest
>&2 echo Exit called label with errorlevel 1. This line is to stderr.
pause
exit /b 1
:HelpScrn
echo Help. Exit with implicit 0.
pause
exit /b
The above uses call to access each label. Exit of a called label
returns back to the point of the call. The menu is in a loop so it keeps
showing until you input 5 to exit the script.
I added pauses into the labels so you could see the messages before clr
is called.
