The command D, available only on the Japanese Katakana model, allows the operator to specify
a two-character sequence that is written to the entire screen. This pattern could then be used to
check display parameters such as geometry, size, and forms.
The CD verb is terminated by entry of@.
When using the CD verb, the display screen initially contains the data written by the most
recently completed test. If a particular pattern is desired, it can be quickly initialized using the
CD-F command or by executing test E4 of the diagnostic (character test).
