Papercount is a number that varies. Papercount is 6.
Burningness is a kind of value. The burningnesses are flaming and notburning.
The scrap of paper has a burningness. The scrap of paper is notburning.
Every turn when the the scrap of paper is flaming and papercount > 0: now papercount is papercount - 1.
Every turn when the scrap of paper is flaming and papercount = 0: now the scrap of paper is nowhere; now papercount is 6.
Problem. You wrote ‘Every turn when the scrap of paper is flaming and papercount = 0’ : but I don’t understand the ‘when/while’ clause, which should name activities or conditions.
See the manual: 18.4 > 18.4. While clauses
