Get a list of all the Starter flows in a model

RemoveLeaves(EventLogById(1).Flows:From.Where(IsNull(_)))

Go through the model recursively using the flows:

RemoveLeaves(EventLogById(1).Flows:From.Where(IsNull(_))).To.OutgoingFlows.To.OutgoingFlows.To

Traverse the model using events:

RemoveLeaves(EventLogById(1).Flows:From.Where(IsNull(_))).FlowOccurrences.To.NextInCase.NextInCase.NextInCase

All case attribute values within the model grouped by case attribute types.

Let("cases", EventLogById(1).Cases, EventLogById(1).CaseAttributes:(Let("attribute", _, cases.Attribute(attribute))))

All event attribute values within the model grouped by event attribute types.

Let("events", EventLogById(1).Events, EventLogById(1).EventAttributes:(Let("attribute", _, events.Attribute(attribute))))

Define new user defined functions:

Def("First", "a", GetAt(0, a));
Def("Second", "a", GetAt(1, a));

Array(First(a), Second(a))

Def("x", "a", Distinct(RecurseLeaves(OrderBy(EventLogById(a).Cases.Events, Type.Name), Type.Name)))

Function definition that uses itself, i.e. recursive functions:

Def("Fib", "a", If(a < 2, 1, Fib(a - 1) + Fib(a - 2)));
For("i", 0, i < 10, i + 1, Fib(i));
