• When a Database Restore operation is performed the files from the selected directory or floppy disk will be
copied into the
working directory, overwriting the current files in the directory. It is imperative that this
operation be performed with the confidence that the files in this working directory are not needed because
they cannot be retrieved without specific retrieval steps that require DOS operations outside of the PC-DBA
program environment.
• Press
Y. The files are copied into the working directory. When complete the following screen displays:
Copy Complete, Old Data Files Are Renamed to '.BAK'
Press Any Key To Exit
• Press any key. The restored files are now available for editing.
• Enter into Database Programming to edit as required.
PC-DBA Control Menu
• At the bottom of the PC-DBA screen, special control functions of PC-DBA are shown. The following line/bar
can be found at the bottom of the display:
F1-Help F2-Unsave F3-RCV F4-SND F5-Cnt F6-Disc F7-Prn F8-Init F9-Mdm F10-
RS232C
• Use the associated “F” (Function) keys on the PC keyboard to access the various operations. The functions
and their specific operation is detailed in the text below.
F1 – Help
• Press F1 to view the keystroke help menu of PC-DBA. There are two help screens.
F2 – A-Save/U-Save
• Press F2 to select Auto-Save or U-Save (You-Save). This selection determines how PC-DBA will save data
during the programming process. The current mode of operation displays.
• If U-Save is selected, PC-DBA prompts the user to confirm the save operations. During the save process,
changed data is written over existing data files to store the changed data. For this reason the user must be
confident that previous data values are no longer required. Once the new data is written, the old data is lost.
(See Database Save for instructions on how to save old data.)
