Each group of buffer memory addresses storing a complete warning history record is assigned a pointer No.

Example: Pointer No. 0 = Buffer memory addresses 4158 to 4161, 4272, 31316

Pointer No. 1 = Buffer memory addresses 4162 to 4165, 4273, 31317

Pointer No. 2 = Buffer memory addresses 4166 to 4169, 4274, 31318

Pointer No. 15 = Buffer memory addresses 4218 to 4221, 4287, 31331

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.)
