System status information -You are using RSTS/E Version 9.0 software. At the present day and time (09-Jun-85, 05:50 PM) the system has been operating for 6 hours, 22 minutes, and 19 seconds (Up: 6:22: 19).®
Job - There are five attached jobs now in use on the system.®
Who - This column displays the accounts to which the jobs belong.@) Where - This column displays the keyboards controlled by the jobs. The asterisk (*) following KB30 indicates a dial-up line.
®
What - Various operations (SYSTA T, BACKUP) are being performed.®
Size - These numbers indicate both the actual size of your job, as well as the size to which the job can expand. The size is shown in thousands of words -or K w-ords - of computer storage space. A word is a unit of storage in the computer that holds 16 bits, or 2 ASCII characters, of information. Incomputing, K approximates thousand-word units of memory storage (actually 1K= 1024 words). The Size column is mainly to tell you the load each job places on the system.
(j) State - The status of each job is determined by the operation being
performed. For example, the SYSTAT job's status is RN Lck. This means that the job is running or waiting to run (RN), and that it is locked in memory (Lck) during the SYSTAT operation. The SYSTA T operation is completed when the display appears at your terminal and is followed by the DCL prompt, which shows that your job is no longer locked in memory .
. ®
Run-Time - The system keeps track of the CPU time each job uses. For example, the BACKUP job has used a total of 8 minutes and 13 seconds of CPU time.®
RTS (Run-Time System) - RSTS/E provides a variety of run-time systems, including DCL and null RTS (shown on the display as " ... RSX").4-4 System and Account Operations
