Supplementary description

(ii)
When all B, X(U) , and Z (W) of the second
straight line are specified, the first straight
line may provide one of the A, 1, and K
commands.
The taper multiple cornering command
specifies the first and second and straight
lines by selecting addresses X, Z, 1, K,
A, and B. Hence, unlike the other G com-
mands, X, Z, I, K, and B do not allow the
omission of “ 0“ specification.
The speci–
fication of “ O“ have different meaning for
X, Z, I, K, and B.
IIo!! should always be
specified.
