1. It may be that the user is reconfiguring the system with the explicit intent of changing the dataflow dependencies; thus, the off-line tests are used only as warnings of possible incompatibility.

3. Where appropriate, the name of a variable ν ∈ Ν (ν.name) is distinguished from the value of the variable (ν.val).
4. If a code block both writes to thread variables and pushes an operation sequence onto the operation stack of the thread while operation p is delivered, then the operations in the pushed sequence begin executing only after p completely executes. The thread variables written by p, therefore, are visible to the operation sequence pushed by p.
5. When the boundaries of an atomic state change must extend beyond a single operation delivery, multidelivery locks can be used as described in a later section.
6. Dataflow dependencies can be formally defined between an operation q and an earlier operation p with respect to a particular thread variable ν.
7. This situation can be compared to a series of nested function calls: The return value for the innermost function call only propagates to the topmost level if it is returned unmodified by each function call in the chain.
8. Since each code block exists in one and only one element, operation-to-element bindings can be derived from the Bird-Code function.
