Need to convert lab from UNIX to DOS

Question

I need to convert this lab from Unix so that it will run as a batch file in Windows (substitute with the appropriate commands). (I will definitely be starting some UNIX classes soon).
FILE=${1:?'Parameter 1 should be set to file name'}
BLOCK=${2:?'Parameter 2 should be set to block to be corrupted''}
BLOCKSIZE=${3:?Parameter 3 should be set to blocksize'}
dd of=$FILE bs=$BLOCKSIZE conv=notrunc seek=$BLOCK <<EOF
CORRUPT
EOF
dd of=$FILE bs=$BLOCKSIZE conv=notrunc seek='expr 1 + $BLOCK' <<EOF
CORRUPT
EOF
dd of=$FILE bs=$BLOCKSIZE conv=notrunc seek='expr 2 + $BLOCK' <<EOF
CORRUPT
EOF
dd of=$FILE bs=$BLOCKSIZE conv=notrunc seek='expr 3 + $BLOCK' <<EOF
CORRUPT
EOF
