?
Count i while ?????????????????
}
Write ????

Works for 1 to 10, with ? as the hidden character.

Original solution:

1
Count i while _/10 {
Write 49
0
}
Write 48+_

The initial accumulator value goes from 1 to 9 and then to 99. Whenever it is less than 10, _/10 is 0 and the loop doesn't execute. When it is greater than 10, the inner loop writes a 1 and sets the accumulator to 0, which breaks out of the loop and writes a 0.
