Go Back to Start If no input is entered (Bat File) (#2)

This is 开发者_运维百科a to follow-up question: Go Back to Start If no input is entered (Bat File) Now for another final Touch and my file is perfect :) Here's the relevant code part:

:: Delete variable %F%
SET "F="
set /p F=Folder or a File Trget:
attrib +s +h +r %F%

IF I Set Non Input, the file makes all the relevant files in the same folder and with the same extension (as in attrib +s +h +r *.bat) ,(in this case, bat) in to system files

I apologize for the bad wording

The complete procedure of this script (it's not the all script onlly on part of it)

:Hide
@echo off
cls
Color 0c

ECHO.
ECHO.
:: Delete variable %F%
SET "F="
set /p F=Folder or a File Trget:
attrib +s +h +r %F%


@echo off

1. Always take filename it quotes becouse it can have spaces.

2. Delete quotes from filename. More: set /?

   set F=%F:"=%
   

3. 1. Make sure the input is not empty. Command 'if not "%F%"==""' - checks that input isn't empty. Command 'if EXIST "%F%"' checks that file exist.

      :: Delete variable %F%
      SET "F="
      set /p F=Folder or a File Target:
      set F=%F:"=%
      
      if not "%F%"=="" if EXIST "%F%" attrib +s +h +r "%F%"
      

   2. If you have too many commands that can't be runned without input you can add procedure in end of file and call it

      if not "%F%"=="" if EXIST "%F%" call :HideChecked
      
      :: There are your code. Remember, that call :Label always returns back & keeps batch execution. Read more: call /?
      :: So there your code ends. And new procedure starts.
      
      :: Prevent crazy parsing
      exit /b
      
      :HideChecked
          attrib +s +h +r %F%
      :: exit /b == return back
      exit /b
      

4. Always say to user, where is his error

   if not "%F%"=="" if EXIST "%F%" call :HideChecked
   
   if "%F%"=="" (
       echo You must choose something
       REM in 'IF ()' your can use only REM for comments.
       REM >nul - means command 'pause' will print nothing (except errors)
       pause>nul
       goto Hide
   )
   if NOT EXIST "%F%" (
       echo No such file. File list:
       REM dir /? for help
       dir /P/B
       pause>nul
       goto Hide
   )
   

5. In start of file add 'goto Input'. After each procedure (:Hide :Show :Exit) add 'goto Input' to prevent crazy parsing.

   :: At start of file
   goto Input
   
   :: There can be some code
   
   :Show
       :: And there
   goto Input
   
   :Hide
       @echo off
       cls
       Color 0c
   
       ECHO.
       ECHO.
       :: Delete variable %F%
       SET "F="
       set /p F=Folder or a File Target:
           set F=%F:"=%
   
       if not "%F%"=="" if EXIST "%F%" call :HideChecked
       if "%F%"=="" (
           echo You must choose something
           REM in 'IF ()' your can use only REM for comments.
           REM >nul - means command 'pause' will print nothing (except errors)
           pause>nul
           goto Hide
       )
       if NOT EXIST "%F%" (
           echo No such file. File list:
           REM dir /? for help
           dir /P/B
           pause>nul
           goto Hide
       )
   
   goto Input
   
   :Input
                       @echo off
       CLS
       ECHO.
       ECHO.
       ECHO   ######################################################
       ECHO   #                                                    #
       ECHO   # 1 - Set Other System Attribute To a Folder or file #
       ECHO   # 2 - Remove System Attribute From a Folder or file  #
       Echo   # 3 - Exit                                           #
       ECHO   #                                                    #
       ECHO   ######################################################
       ECHO.
       ECHO.
   
       :: Delete variable %A%
       SET "A="
       SET /P A=Set Your Choice And Press Enter: 
   
       IF "%A%"=="1" GOTO Hide
       IF "%A%"=="2" GOTO Show
