Slowly extend the ram fully and make sure that it does not touch other parts. Verbs RULE: 5.4 In an instruction, write the verb in the imperative ("commanding") form. In procedures, the verbs you use must always be in the active voice (refer to Rule 3.6). Procedures can contain: Descriptive text, where the verb is in the third person singular ("he", "she", "it") or plural ("they"). Instructions, where the verb must be in the imperative ("commanding") form. An instruction in a procedure tells the reader to do something. Two things are important about instructions: The verb is in the imperative ("commanding") form (as though "must" were written in front of it) The subject of the verb is implied as "you", but is not necessarily written into the sentence. Examples: Set the switch to ON = (You must) set the switch to ON. Remove the bolts = (You must) remove the bolts. Be careful with the concentrated acid = (You must) be careful with the concentrated acid. It is better to write the verb in the imperative ("commanding") form because this emphasizes that the operator must do a certain action. Other, less direct forms of instructions leave confusion as to whether something: Must be done Is already done Must be done in the future by someone else. Example: WRITE: Continue the test. NOT: The test can be continued by the operator. |
