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.)
