Pointer No. 1 = Buffer memory addresses 1362 to 1365, 1473

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.)
