Step 1: Calling Files

first of all im going to tell you about the call method. the call method allows a batch file to run(or call) the other file in the same file.

for example, in the first file(you can put anything you want to be remembered. name it what your username was for me it would be gram.bat):

set user=gram
set pass=1234

and in the second file(you can name it whatever you want):

@echo off
:main
cls
echo 1.)login
set  /p var=
if %var% == 1 goto login
goto main


:login
cls
echo username?
set /p use=
call %use%.bat
cls
echo password?
set /p pas=
if %pas% == %pass% goto loged
cls
echo wrong password/username
pause >nul
goto main

:loged
cls
echo what you want when you log in
pause >nul
goto loged


and that is how to use the call method in the next step ill teach you how to write in files.

Step 2:

writing to files is very simple. if you want a username to be set you can use this(name is the file you want it to be written to):

echo set user=gram >> name.bat

the echo is writing what goes after it.
>> is inputting it into the file name.bat

an example for the last program would be adding this in:

:reg
cls
echo set your username:
set /p user=
cls
echo set your password:
set /p pass=

echo set user=%user% >> %user%.bat
echo set pass=%pass% >> %user%.bat

goto loged
