DX-80 Programming Manual
- 34 -
When the system performs a database restore operation it copies the files from the selected directory or
floppy disk into the working directory on your laptop, overwriting the current files in that directory.
4. Press Y . The system copies the files into the working directory. When this is done, PC-DBA displays the fol-
lowing message.
Copy Complete, Old Data Files Are Renamed to '.BAK'
Press Any Key To Exit
5. Press any key. The restored files are now available for editing.
2.1.4 PC-DBA CONTROL KEYS
Special control functions of PC-DBA are shown at the bottom of the PC-DBA screen.
F1-Help F2-U-save F3-RCV F4-SND F5-Cnt F6-Disc F7-Prn F8-Init F9-Mdm F10-RS232C
Use the associated function keys across the top of the PC keyboard to access the various operations.
2.1.4.1 F1 – Help
Press F1 to view the keystroke help menu of PC-DBA. There are two help screens.
2.1.4.2 F2 – A-Save/U-Save
Press F2 to select A-Save (Automatic Save) or U-Save (User Save). This selection determines how PC-DBA will
save data during the programming process. The system displays the current setting for this key, i.e., A-Save if
automatic save is set or U-Save if user save is set.
If you select U-Save , PC-DBA prompts you to confirm all save operations. During the save process, the system
writes the changed data to the working directory, not to system memory on the switch. When you have finished
programming, you must perform a SAVE operation (part or all) to send the modified data in the working directory
on the laptop to the system memory on the switch. Once the system saves the new data in system memory, the old
switch data is lost.
CAUTION
It is imperative that you are sure you no longer need the files in the
working directory. You cannot retrieve them later without using
specific DOS retrieval steps outside of PC-DBA.
