Error Recovery
G.6 RECOVERING BUFFERED DATA
If ILOterminates abnormally while data is being buffered to the mass storage device, the file ELIF FEF:
in memory will contain the readings that have not been stored in the final data file. These readings are
not in a form that may be read by FEFIIET, and must be moved to the data file once the system is
working again. The process of moving the data consists of the following steps:
e Identify the data file on the mass storage device.
e Determine the data file's size, structure, and amount of room remaining.
e Ensure that the data records in the file ELIF EF match the structure of the destination
data file, and that there is sufficient room in the data file to hold the buffered data.
e Move the buffered records to the destination file and update the data record count.
The program MEF GEELIF in the Data Acquisition Pac may be used to recover the data in ELIF FER. To
use the program, restore the HP-71 system to working order and run MERGEELIF:

Run the FIER GEELIF program.
The program asks for the name of the destination data
file.
Enter the file name, including the device specifier
eg: MYVFILE: THFE.
The program reads the data file and the file ELIFFEEFto
determine if the structure of the two files match.
The program displays a status message while the data file
1s updated.
The program is finished.
