  hey guys, im a batch enthusiast and i have had my experiences in batch, like i made tic-tac-toe from scratch, but this one really puzzles me.

  im trying to make a login thing, because im really just an enthusiast and i like making stuff and showing my friends

  and im been searching and you have to use the 'for' command, yeeeaaahhh well, that doesn't work for me, and i don't know why :'_(

  this is what i have

  @echo off
  :start
  cls
  echo. 
  echo login thing
  echo.
  echo 1)create account
  echo 2)login
  echo.
  set /p log=
  if %log% equ 1 goto create
  if %log% equ 2 goto Login
  if %log% gtr 2 echo Thats an invalid choice.
  :create
  cls
  echo.
  echo create account
  echo.
  set /p UN=Username:
  set /p PW=Password:
  echo.%UN%> "C:\Users\[Computer]\Desktop\Stuff\New folder\Login.txt"
  echo.%PW%>> "C:\Users\[Computer]\Desktop\Stuff\New folder\Login.txt"
  echo.
  PAUSE
  goto start
  :Login
  cls
  set confirm=0
  echo.
  echo LOGIN
  echo.
  set /p UNL=Username:
  set /p PWL=Password:
  for /f %%a in (Login.txt) do set UNLC=%%a
  echo %UNLC%
  pause
  if %confirm% equ 2 goto GRANTED
  if not %confirm% equ 2 goto DENIED
  :GRANTED
  cls
  echo.
  echo ACCESS GRANTED
  echo.
  PAUSE
  exit
  :DENIED
  cls
  echo.
  echo ACCESS DENIED
  echo.
  echo Press any key to retry
  echo.
  Pause >nul
  goto Login
  
  

  im trying to get it so that it reads the first 2 lines from the text file, which has the username and password, so that if it doesn't match up..... access denied, etc, but for me it doesn't work, i may be 13 but im quite smart, i didn't think i would need to make a thread on a forum, but none of the ones i have gone to have worked for me, what happens is it always reads the second line :( and i don't know why, the for command doesn't work for me, and nothing i add to the command will make it work, im wondering if someone can change my code a bit so i can understand it, and so it works and also why can't you have the full file location the brackets ie. for /F %%a in ("C:\bla\bla\bla") do bla bla bla. is says the file cannot be found, wtf. :( so im saddened by the fact that my thing won't work and that i have to go and make a thread for something that is really easy, to others, but for me, reading something out of a text file on batch, is harder than you think. :(please help me, abd if you have to change the ENTIRE code if i have also done something wrong, I've also changed my computer name and taken some parts of the code out (took them out a while ago). so please if you can help me, i would HIGHLY appreciate it, thanks :D 

  also i have Acer Aspire 5750, 64bit, Windows 7 Service Pack 1.
