The input to the INCKS card is frequency-synchronized and can
be selected manually by the Advance Sync button on the 
FB-20922-A card (Figure 4.11). Pushing the button selects the next
highest 
SINX input from the one in which the clock card is
currently locked. One of the four 
SINX channels can also be
selected by writing onto the data base. A bad input cannot be
selected by programming. The card will always automatically
release its frequency synchronization mechanism from a faulty
SINX...

Tones and Tone4.7 Table 4.3 defines the digitally generated tones supplied
Generationby the OMNI SI. These tones are used in the normal operation of
various features.
Memory Page Card4.8 The selector switch (Figure 4.12) on the Memory Page card
MPG16(FB-17213-BOA) is for manual selection of the memory data

Mass Storage4.9 This paragraph describes the mass storage for the system’s
software.
Disk Subsystem4.9.1 The 
OMNI SI uses the disk subsystem for system loading,
data base back-up, and loading of recent change overlay
programs. The hard disk (Figure 4.13) stores program and data
images associated with the...

NOTE: See section 6.0 for information on the disk subsystem for
a system containing the PD-200 data option. In addition,
the hard disk contains the Recent-Change and off-line
maintenance programs which are paged into memory
for execution.
The system uses a 1 O-megabyte, Winchester-type 5-l 
14 inch
hard disk drive with or without the data option. The floppy disk
(Figure 4.13) is a 
5-l/4 inch industry standard. The floppy disk
has a capacity of one million bytes of unformatted information...

File Management4.9.2 Random access to files can be supported with disk
Systemstorage. The FMS (File Management System) software manages
all data storage and transfer on the system disks. Simultaneous
access to a single file, along with multiple open files, is possible.
Opening a file causes a FID (File Identity) to be associated with
that file. FMS calls use the FID to identify the file being
accessed.

the disk with the attributes and name given in the command.
With completion of the command, the file opens for the access
method specified in the FCB.

DescriptionsQ Delete Command. The Delete command deletes a file from
the disk by removing its entry in the Disk File Directory and
deallocating the storage used by the file.
* Rename Command. The Rename command can change the
name of a disk file.
