The rack database files are stored in d:\library\system\rack, where
rack" is the name of the rack. The rack database files define the
modules, tasks, and variables in the rack. The \rack subdirectory
includes the source code, object code, cross reference files, and
documentation files for the application tasks in the rack.
Backup of the AutoMax Executive software library directory and all its
subdirectories should be done on a regular basis using the DOS
XCOPY command.
4.3 Database Files
The AutoMax Executive software stores the data for AutoMax systems
in dBASE IIIĆcompatible database files. There are four databases for
each system and five databases for each rack in a given system.
Database files are designated by a dollar sign ($) as the first
character of the filename and a .DBF extension. Index files (which
contain pointers to where in the database information is stored) also
have a dollar sign ($) as the first character of the filename, but they
are assigned a .NDX extension.
For each system:
$SYSTEM.DBF
$SYSTEM1.NDX defines the system
$SECT.DBF
$SECT1.NDX defines the sections in the system
$RACK.DBF
$RACK1.NDX
$RACK2.NDX defines the racks in the system
$NET.DBF
$NET1.NDX
$NET2.NDX
$NET3.NDX defines the networkĆwide variables in the
system
For each rack in a system:
$CARD.DBF
$CARD1.NDX defines the modules in the master rack and
any remote racks
$IORACK.DBF
$IORACK1.NDX defines any remote racks connected to the
rack
$TASKS.DBF
$TASKS1.NDX defines the tasks in the rack
$SWVAR.DBF
$SWVAR1.NDX
$SWVAR2.NDX
$SWVAR3.NDX defines the variables configured in the rack
$PARAM.DBF
$PARAM1.NDX defines parameters for UDC module
