Indicates a pointer No. that is next to the Pointer No.
assigned to the latest of the existing error history records.
Each group of buffer memory addresses storing a complete error history
record is assigned a pointer No.
Example: Pointer No. 0 = Buffer memory addresses 1293 to 1296
Pointer No. 1 = Buffer memory addresses 1297 to 1300
Pointer No. 2 = Buffer memory addresses 1301 to 1304
Pointer No. 15 = Buffer memory addresses 1353 to 1356
Each history record is assigned a pointer No. in the range between 0 and 15.
If the pointer No. 15 has been assigned to a new record, the next record will
be assigned the pointer number 0.
(A new record replaces an older record when a pointer No. is reassigned.)
