Repeat part of program while other part stays the same

Question

I made a chat program and I want it to auto refresh so i can get rid of the refresh option I have on it. the only problem is I would need to have everything from :A all to way to Echo -----.... to repeat itself while everything below does not. And I do not want it to be split into 2 files.

 :A
    cls
    Echo Server: %S%
    Echo Press Q to Quit Or Press R to refresh chat log.
    echo ---------------------------------------------------------
    type %S%.txt
    echo ---------------------------------------------------------
    set /p M=Enter Your Message:
    if "%M%"=="Q" goto B
    if "%M%"=="q" goto B
    if "%M%"=="R" goto A
    if "%M%"=="r" goto A
    echo %U%: %M% >>%S%.txt
    goto A

Note

• if /I Do a case Insensitive string comparison ;
• :eof This predefined label will exit the current routine ;
• call :label Jump to a label (subroutine) in the current batch script .

Next code snippet could help.

:A
    call :repeatHeader
    set /p "M=Enter Your Message: "
    if /I "%M%"=="Q" goto :B
    if /I "%M%"=="R" (
        call :refreshLog
        goto :A
    )
    echo %U%: %M% >>%S%.txt
    goto :A

:repeatHeader
    Echo Server: %S%
    Echo Press Q to Quit Or Press R to refresh chat log.
goto :eof

:refreshLog
    cls
    echo ---------------------------------------------------------
    type %S%.txt
    echo ---------------------------------------------------------
goto :eof

:B
