Each job as it progresses through the Schedule System, it makes a series of queue changes (e.g. `Ready to submit', `Completed', etc.). Each queue change is recorded in the historical data file.
To view historical data about a particular job use a command of the following format.
C:\> schedule type/history job_name
For example:
C:\> schedule type/history \demo.a\start/queue=(r,u)
\demo\a\start
