Creating a Windows batch file that accepts parameters

Question

I want to create a Windows batch file that accepts parameters and uses it inside. For instance, when I type "sample.bat -username admin -password pass123" in the command line, it will store "admin" and "pass123" in the variables inside sample.bat

This is how I do it in Linux:

USERNAME=
PASSWORD=

while [ $# -ne 0 ]
do
case $1 in
    -username*)
        USERNAME=$2
        ;;
    -password*)
        PASSWORD=$2
        ;;
    *)
        ;;
esac
shift 1
done

I'm not used to making scripts in Windows but I need to do a Windows counterpart for this one. Kindly help me. Thank you so much!

@echo off
set user=
set pass=

:loop 
if "%1" == "" goto done
if /i "%1" == "-username" set "user=%2"
if /i "%1" == "-password" set "pass=%2"
shift
goto :loop

:done
echo Username:  %user%
echo Passoword: %pass%

Note: don't use %username% as a variablename, because it's a systemvariable.

As they are, the two shifts can generate an error. If arguments are data -username myname, user name will not be retrieved.

yes, that's what came to my mind tonight ^^ - I'll change that.
