  2. SPLIT


The SPLIT instruction causes the runner to duplicate its entire state a number of times at a specific point. Each copy of the runner will have SPLIT and SPLIT_NUM environment variables automatically set. The former will be the index of the runner, and the latter will be the number of copies.


  • Use SPLIT 3 and three copies of the runner will have ENV SPLIT=0 SPLIT_NUM=3 and ENV SPLIT=1 SPLIT_NUM=3 and so on.
