The Error Log Area can be moved to the DM or EM Areas and its size can be
increased to store up to 2,047 records with the PC Setup.
With the default PC Setup, error records occupy five words each stored between
words A100 and A199. The last record that was stored can be obtained via the
content of word A300 (Error Record Pointer). The record number, Auxiliary Area
words, and pointer value for each of the twenty records are as follows:

*The pointer value is in word A300, which is in the read-only area (words A256 to A511).
Although each of them contains a different record, the structure of each record is
the same: the first word contains the error code; the second word, the error con-
tents, and the third, fourth, and fifth words, the time, day, and date. The error
code will be either one generated by the system or by FAL(006)/FALS(007); the
time and date will be the time and date from the Calendar/Clock Area, words
G001 to G004. This structure is shown below.

Operation
When the first error code is generated, the relevant data will be placed in the er-
ror record after the one indicated by the Log 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.
