Indicates a pointer No. that is next to the Pointer No.
assigned to the latest of the existing warning history records.
Each group of buffer memory addresses storing a complete warning history
record is assigned a pointer No.
Example: Pointer No. 0 = Buffer memory addresses 1358 to 1361
Pointer No. 1 = Buffer memory addresses 1362 to 1365
Pointer No. 2 = Buffer memory addresses 1366 to 1369
Pointer No. 15 = Buffer memory addresses 1418 to 1421
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.)
