After reading how Paul Kline's
slowQscan achieves extra scans, I wondered how well a similar technique would work in '88 Standard Redcode. Previously published '88 quick-scanners include:
Using Kline's technique 36 scans are possible in 48 instructions:
qfirst equ (qp2+2*qstep)
qdist equ qfirst+111
qstep equ 222
qi equ 7
qr equ 7
qbomb dat <qi/2-qi*qr, <qi*qr-qi/2
qa equ qstep*16
qb equ qstep*5+2
qc equ qstep*10
qd equ qstep*2
qe equ qstep*1
qgo cmp qdist+qc, qfirst+qc
jmp qfast, <qa
cmp qdist+qe+qd, qfirst+qe+qd
qp1 jmp <qfast, <qc
qp2 cmp qdist, qfirst
qp3 jmp qskip, <qe
