Student information is being held in a data area, where each student record has the following format:
The first nine bytes are the student number, held in ASCII
The next byte is the course mark
The next word is the section identifier
There are well over three hundred such student records that have been loaded sequentially into memory starting at address $10000. The last record loaded is a dummy record with a section identifier of $FFFF, to show the end of the records.
If a2 has the address of a student record, what is the index value Y such that Y(a2) addresses the section identifier?
Y = 10 or $0A
