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.)
