Wanted: Help translating from bash to cmd.exe

How do I translate this from bash to cmd.exe:

../myprogramreadsstdin <<EOF

this is data read by my program

bash sends my program and end-of-file signal

when it sees the following token:

EOF

../myprogramreadsstdin <<XYZ

this is data read by my program. bash sends an end-of-file signal

when it sees the following string:

XYZ

Thanks!
