APPENDIX C
- SYSTEM ERROR CODES
Errors entered by the operator are normally trapped
by the program logic and an appropriate error message is displayed (usually in
red if you have a colour screen). However, there is another class of errors
that HiFinance traps. These are called file errors. These errors can be
generated in several ways, eg power faults during updating, a completely full
hard-disk, a network error, etc.
When a file error is detected, HiFinance will pass
control to an error handling routine. This program leaves the screen intact,
except for the bottom two lines that are used to displayed the name of the file
found to be in error, the error code and a short description of the error
condition. The computer will beep continuously to further alert you to the fact
that there has been an error. The beeping can be stopped by pressing any key,
eg. <Enter>.
The steps to be
taken by the operator are as follows:
Firstly, press any key (eg. <SPACE>) to stop the beeping.
Next make a note of the error message and
explanation. Also, note the part of the program you were in so that a recovery
procedure can be initiated. In DOS you have the option to print the screen
using the <Shift> and <PrtSc> keys. This will produce a permanent record of the
error onto your printer. If your default printer is a laser type, this
procedure might not actually print a page until you force a page feed.
The program can be terminated by pressing <Ctrl><K>.
Recovering
from a system crash.
Generally, the safest way to permanently correct the
fault is to restore your files from your latest backup. This will, of course,
remove any transactions entered since the last backup was taken. It is thus
useful to firstly print your AUDIT TRAIL,
if possible. Any other course should not be attempted without reference to your
dealer.
If the error is due to a disk full situation, check
that you have not filled the disk with word-processing files or games. If you
have indeed exceeded the limit of your hard disk, you will need to either
increase the hard-disk capacity of your computer or delete some files. In
either case, restoring your files will not directly solve your problem and you
should contact your dealer for advice.
