r,3
Up to twelve 4-bit characters (most significant char-
acter at address m) is subtracted from E. Difference
appears in E. (D) register specifies field length.
7-47
SCA.I 36 m,b
Where (M) contains a "1" bit, complement the cor-
responding bit in A 7-37
SCAO 13.4-7 y,b
Shift (AO) left end around until upper 2 bits of A are
unequal. Residue K = k-shift count. If b = 1, 2, or 3,
K
--->
B b; if b = 0, K is discarded 7-52

(AOO-16) ~ (MOO-16) 7-25
SCIM 77.53 x
Selectively clear Interrupt Mask Register for each
"1" bit in x. The corresponding bit in the mask register
is set to "0" 7-66
SEL 77.1 x,ch
If channel ch is busy, read reject instruction from
P + 1. If channel ch is not busy, a 12-bit function
code is sent on channel ch with a function enable,
RNI @ P + 2 7-70
SET
70.7 y
Set (D) with lower 4 bits of y
7-46
SFE 70.0-3 k,b
Shift (E) in one character (4-bit) steps. Left shift: bit
23 = "0", magnitude of shift = lower 4 bits of K = k
+ (B
b
). Right shift: bit 23 ="1", magnitude of shift=
lower 4 bits of complement of K = k + (B
b
)
7-49
SFPF 77.71
Set floating point fault logic 7-67
SHA 12.0-3 y,b
Shift (A). Shift count K = k + (B
b
) (signs of k and Bb
extended). If bit 23 of K = "1", shift right; comple-
ment of lower 6 bits equal shift magnitude. If bit 23
of K
=
"0", shift left; lower 6 bits equal shift magni-
tude. Left shifts end around; right shifts end off
7-50
SHAO 13.0-3 y,b
Shift (AO) as one register. Shift count K = k + Bb
(signsofkand Bbextended).lfbit 23 of K="1", shift
right and complement of lower 6 bits equal shift mag-
nitude. If bit 23 of K = "0", shift left and lower 6 bits
equal shift magnitude. Left shifts end around; right
shifts end off 7-52
SHO 12.4-7 y,b
Shift (0). Shift count K = k + (B
b
) (signs of k and Bb
extended). If bit 23 of K = "1", shift right; comple-
ment of lower 6 bits equal shift magnitude. If bit 23
of K
=
"0", shift ieft; lower 6 bits equal shift magni-
tude. Left shifts end around; right shifts end off
