volví a leer tu post y creo que lo que tu pedias es esto:

@echo off
echo Script Mayus
echo -------------
echo.
echo.
echo Introduce una palabra o frase:
set /P inputstring=
echo.


if %inputstring:minus=%==%inputstring% goto sin_minus
set inputstring=%inputstring:minus=%
set inputstring=%inputstring:a=A%
set inputstring=%inputstring:b=B%
set inputstring=%inputstring:c=C%
set inputstring=%inputstring:d=D%
set inputstring=%inputstring:e=E%
set inputstring=%inputstring:f=F%
set inputstring=%inputstring:g=G%
set inputstring=%inputstring:h=H%
set inputstring=%inputstring:i=I%
set inputstring=%inputstring:j=J%
set inputstring=%inputstring:k=K%
set inputstring=%inputstring:l=L%
set inputstring=%inputstring:m=M%
set inputstring=%inputstring:n=N%
set inputstring=%inputstring:ñ=Ñ%
set inputstring=%inputstring:o=O%
set inputstring=%inputstring:p=P%
set inputstring=%inputstring:q=Q%
set inputstring=%inputstring:r=R%
set inputstring=%inputstring:s=S%
set inputstring=%inputstring:t=T%
set inputstring=%inputstring:u=U%
set inputstring=%inputstring:v=V%
set inputstring=%inputstring:w=W%
set inputstring=%inputstring:x=X%
set inputstring=%inputstring:y=Y%
set inputstring=%inputstring:z=Z%

echo La vamos a pasar todo a mayusculas
echo.
echo la palabra o frase en mayusculas es: %inputstring%
goto fin
:sin_minus
echo.
echo.
echo la palabra o frase es: %inputstring%
:fin
echo.
echo.
echo pulsa una tecla para finalizar
pause > nul

Por cierto, te recomiendo que pongas a los posts sucesivos títulos más apropiados, p.e: Pasar de minúsculas a mayúsculas con script bat o cmd
