Error message examples
The value of Variable A is being used by B before it has been set. The value of A should be set by B, and cannot be used directly or indirectly by B until it has already been set.

Definition of Object A:
ComputedBy(B)
Definition of Object B:
Var x := A + 5; A := 417; ...
Remedies
Correct the definition of the object responsible for computing the value of the another variable so that it sets the variable before it uses it.
