OpDrilling

Variable: State.OpDrilling

Type: Boolean

State variables are all boolean type variables. That is, they only take the value “true” or “false”. Therefore, words are not formed from these variables. “State.OpDrilling” variable becomes “true” at the beginning of the drilling operations. It becomes “false” again at the beginning of the first non-drilling operation, which comes after the drilling operations.
