Channel Number of the channel
Window Address of the window control block (WCB) for
the file if the device is a file-oriented device; zero

I/O operation outstanding; blank otherwise
Device/file accessed Name of the device and, if applicable, name of
the file being accessed on that device
The information listed under the heading ‘‘Device/file accessed’’ varies from
channel to channel and from process to process. SDA displays certain information
according to the conditions listed in Table SDA–20.

Type of Process
dcuu: SDA displays this information for devices that are not
file structured, such as terminals, and for processes that
do not open files in the normal way.
dcuu:filespec SDA displays this information only if you are examining
a running system and only if your process has enough
privilege to translate the file-id into the filespec.
dcuu:(file-id)filespec SDA displays this information only when you are
examining a dump. The filespec corresponds to the
file-id on the device listed. If you are examining a dump
from your own system, the filespec is probably valid. If
you are examining a dump from another system, the
filespec is probably meaningless in the context of your
system.
dcuu:(file-id) The file-id no longer points to a valid filespec, as when
you look at a dump from another system; or the process
in which you are running SDA does not have enough
privilege to translate the file-id into the corresponding
filespec.

This table uses the following formulas to identify the information displayed:
dcuu:(file-id)filespec
where:
dcuu: is the name of the device.
file-id is the RMS file identification.
filespec is the full file specification, including directory name.
