鑑賞のポイント

Appreciative Points

Begin with light

letters (‘0’ to ‘9’)

for the first half

Use 0x2C (INC L)

instead of 0x23 (INC HL)

for the strength at the

center of ‘Tanka’

Smooth flow with

small values Terminate with big

values representing

‘The End’

Place heavy letters

(‘A’ to ‘F’) at the end

of lines

• In many cases, you can adjust the order of

instructions so that the codes look nice.

• I believe the order here is the best for this program.
