Database organization and management
This command produces a detailed status report, which includes:
•
Total number of records in the database (old + new)
•
Number of new records
•
Total amount of the new data in bytes
•
Number of free records
•
Database utilization in % (i.e. number of all records/ total database capacity).
Total amount of new data in bytes
deserves some explanation. The database
itself keeps the data in records. Each
record occupies a pre-defined amount of
memory space which does not depend on
variable-length fields like ID-code. When
you save the data to the disk or upload it to
the PC, the size of each record will depend
on its content. Total new data size in bytes
tells you the exact size of the data file (in
text format) that will be formed on the
Floppy Disk or PC.
