I noticed that I always forget to write the translations of JBC code while writing the chapters so I might go through and and add translations who knows. But for now I'll just write the code here so people who want to do the translations themselves or just want to know the code can.
JBC is A=A+3 or A=D
A=D
B=E
C=F
D=G
E=H
F=I
G=J
H=K
I=L
J=M
K=N
L=O
M=P
N=Q
O=R
P=S
Q=T
R=U
S=V
T=W
U =X
V=Y
W=Z
X=A
Y=B
Z=C
