For Example:

echo Hello!
pause >nul
:Name
echo What Is Your Name
set /p Input=Name: 
echo so %Input% Is Your Name, right?
echo Rename?
echo 1 For Yes
echo 2 For No
set /p Input=Rename:
if %Input%=1 goto Name

Another Example:

@echo off
echo 1 or 2?
set /p input=Choice: 
if %input%=1 goto Skip
echo You Chose 1
pause >nul
echo So time for stuff
pause >nul
echo Random Stuf
pause >nul
:Skip
echo So that's it.
pause >nul

Goto accepts the use of variable value to act as the label to goto.

Example:

@echo off

echo a = 1
echo b = 2

set /p "foo=Enter option:"
goto %foo%

However, you should check the input so it will not go to somewhere that does not exist. Going to an undefined label will terminate your batch script instantly.
