3.4.9 Disk Files
The GES-1993 maintains a disk file which contains the current Equipment Constant
settings. The file is updated each time the Operator or Host changes an Equipment
Constant. The most recent settings for some of the Equipment Constants are read
from the file when the Equipment is powered-on.
All Event Report definitions, links, and enable status as well as Limits attributes are
also maintained on separate disk files.
