When you type CTRL/T (control-T), the monitor prints status
information pertaining to your job on your terminal. CTRL/T does not
echo on your terminal. There are 11 items of information output to
your terminal. These items are:
1. The incremental daytime (which is the time since you last
issued a CTRL/T or a USESTAT command) or the time since you
logged in if you have not issued a CTRL/T or a USESTAT
command. (For example, Day: :05:43.)
2. The incremental runtime, which is the CPU time used since you
issued a CTRL/T, USESTAT command, LOGIN command, or TIME
command. (For example, Run:0.48.)
3. The incremental disk reads, which is the number of disk
blocks read since you issued a CTRL/T, USESTAT command, LOGIN
command, or DSK command. (For example, Rd:75.)
4. Incremental disk writes, which is the number of disk blocks
written since you issued a CTRL/T, USESTAT, LOGIN, or DSK
command. (For example, Wr:8.)
5. The program name. (For example, SOS.)
6. The memory size. (For example, 12+19P.)
7. The current context number (for example, Ctx:1.)
8. The job state. The job state codes are described in the
SYSTAT command description. (For example, ^C.) An ampersand
after the job state code indicates the job is locked in core.
An asterisk indicates the job is being run or swapped.
9. The program counter, which is the address of the current
instruction. (For example, PC:400275.)
10. The CPU that the job last ran on. (For example, CPU0.)
11. The job state, which can be INPUT WAIT or OUTPUT WAIT. This
item is printed only when you type CTRL/T from user level.
(For example, OUTPUT WAIT FOR TTY21.)
This information can be obtained with the USESTAT command at monitor
level. However, by typing CTRL/T, you can determine your job's
progress without interrupting its execution. When you type CTRL/T,
the character is not passed to your job as an input character.
However, some programs activate a special interrupt feature when you
type CTRL/T. See the TOPS-10 Monitor Calls Manual.
If a system program, such as your text editor uses CTRL/T for another
purpose, you can disable the CTRL/T function using the SET TTY RTCOMP
