 51m comment Can I code a conditional jump in a .nb? To put it clearer. Perhaps (almost surely) it can be done in some twisted way. But it is very, very far from the recommended Mathematica programming practices. If you care to explain your case someone will show you a much better alternative. 2h revised Nested list from a flat folder list deleted 3 characters in body 4h revised Nested list from a flat folder list deleted 123 characters in body 5h comment Changing notations for probability moments with subscripts strongly related.
