how to set mask

[pppp0831]

For each character that you think is a digit, use ?d. If you know parts of it, you can feed that in. Using your example, you can use: 200002?d?d?d?d?d?d?d?d?d2018053019184400100426

But you'll need to guess at how many ?d to use, since you don't know how many characters are missing in there. But the ?d is how you use the digit flag with attack mode 3.

thanks for ur reply,
i am not sure every part 's order,is that  mean i need try every combination ?
