DSD DISPLAYS
You communicate with the system through the console
keyboard and one or more console display screens. The
system provides information about job and system status
through displays on the console screen{s). Data entered
from the keyboard is also displayed. You can request a
permanent record, called a system dayfile, of all
system/console communication.
The two major display programs are system display,
controlled by the DSD prpgram, and control point job
display, controlled by the DIS program (refer to section 5).
DSD controls the display console. The primary functions of
DSD are as follows:
• Maintain a current display of system status.
• Process keyboard entries from the operator.
