The fact that all jobs in a box change status when a box starts running has lead some to use boxes to implement "job cycle" behavior. Be aware that placing jobs in a box to achieve this end may bring with it undesired behavior due to the nature of boxes.
Likewise, you should not place jobs in a box solely because you want to run reports on all of them. When you run autorep on a box, you will get a report on the box and all the jobs in the box (unless you use the -L0 option). In addition, if you use wildcarding when specifying a job name, you could get duplicate entries in your report. For example, suppose you have a box named "acnt_box" containing three jobs named "acnt_job1", "acnt_job2", and "daily_rep". If you specify acnt% as the job name for the autorep report, the report will have an entry for the box "acnt_box" and an entry for each job in the box. Then autorep will continue searching for all job names matching the wildcard characters and, thus, will list "acnt_job1" and "acnt_job2" a second time.
Avoid the temptation to put jobs in a box as a short cut for performing events (such as ON_ICE or ON_HOLD) on a large number of jobs at once. You will most likely find that the default behavior of boxes inhibits the expected execution of the jobs you placed in the box.
