OpPolar ============================================= **Standard Word:** - **Variable:** State.OpPolar **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.OpPolar” variable becomes “true” at the beginning of polar milling operations. It becomes “false” again at the beginning of the first non-polar operation, which comes after the polar operations.
