Area Structure
Error records occupy three words each stored between DM 0970 and DM
0999. The last record that was stored can be obtained via the content of DM
0969 (Error Record Pointer). The record number, DM words, and pointer val-
ue for each of the ten records are as follows:

Although each of them contains a different record, the structure of each re-
cord is the same: the first word contains the error code; the second and third
words, the day and time. The error code will be either one generated by the
system or by FAL(06)/FALS(07); the time and date will be the date and time
from AR 18 and AR 19 (Calender/date Area). Also recorded with the error
code is an indication of whether the error is fatal (08) or non-fatal (00). This
structure is shown below.

Operation
When the first error code is generated with AR 0715 (Error History Enable
Bit) turned ON, the relevant data will be placed in the error record after the
one indicated by the History Record Pointer (initially this will be record 1) and
the Pointer will be incremented. Any other error codes generated thereafter
will be placed in consecutive records until the last one is used. Processing of
further error records is based on the status of AR 0713 (Error History Over-
write Bit).
If AR 0713 is ON and the Pointer contains 000A, the next error will be written
into record 10, the contents of record 10 will be moved to record 9, and so on
until the contents of record 1 is moved off the end and lost, i.e., the area
functions like a shift register. The Record Pointer will remain set to 000A.
If AR 0713 is OFF and the Pointer reaches 000A, the contents of the Error
History Error will remain as it is and any error codes generate thereafter will
not be recorded until AR 0713 is turned OFF or until the Error History Area is
reset.
The Error History Area can be reset by turning ON and then OFF AR 0714
(Error History Reset Bit). When this is done, the Record Pointer will be reset
