batch file ucase question

[kefegg]

Hey guys,
DOS isn't a real programming-thing but I have a question about it and hoped this is the right place.

I want to make a simple batch that reads a .txt file to create folders by what is in that text.file (names of people or chassisnumbers of cars).
But, here comes the question, I want that the folder be created in uppercase text, even if the input is lowercase.

this is what I've got so far.

@ECHO OFF
TITLE create folders
:_start
CLS
SET /P _folder=which folder do you want to create:
IF NOT EXIST %_folder% goto :_notexist
ECHO this folder already exist.
SET /P _question=you want to so what is inside the folder? (Y/N)?
IF /I {%_question%}=={Y} (goto :_show)
IF /I {%_question%}=={N} (goto :_notshow)
:_show
CLS
TREE %_folder%
pause
:_notshow
CLS
ECHO.
ECHO 1. overwrite this folder
ECHO 2. create another folder
ECHO 3. end program
SET /P _mchoice=make your choice(1-3):
IF "%_mchoice%" == "" goto _notshow
IF "%_mchoice%" == "1" goto _notexist
IF "%_mchoice%" == "2" goto _start
IF "%_mchoice%" == "3" goto :eof
:_notexist
CLS
MKDIR %_folder%
FOR /f "tokens=1-7" %%G IN (text.txt) DO @MD %_folder%\%%G" "%%H"
"%%I" "%%J" "%%K" "%%L" "%%M

I found some things about converting low to uppercase but I cannot make things work.

Would appreciate some help but also would like that I still have to think things out (I don't want to be the lazy one )

thanks in regard

For a crude solution:

set folder=%folder:a=A%
set folder=%folder:b=B%
etc.

I thought something like this might work. Listing the complete alphabet is not so bad to do but I wander if there might be a 'smaller' code to write.
Anyway I'm gonna try this one out.
If the output is good, it's good.

muchas gracias!
