Use of Labs as checklists
J labs can be used as a checklist.
Some tasks cannot be automated because input data format is open-ended. If such tasks need to be performed at regular, bust standing relatively far apart, intervals, then checklist can provide necessary guidance and help ensure that critical, but easy to forget steps will be performed. Easiest way to implement checklist in J is use of Labs facility.
Lab describes steps that need to be performed. It may also run preparatory staements, load useful utility scripts, etc.
