RIA {adrs} Test/Branch Skips to {adrs}if register A is not 0, then incre-
37
ments register A by 1. Extend and Overflow are
not effected by the incrementing action, even if a
carry or overflow occurs. {adrs} must be within
- 32 and
+
31 of the current location.
RIB {adrs} Test/Branch Skips to {adrs} if register B is not 0, then incre- 37
ments register B by 1. Extend and Overflow are
not affected by the incrementing action, even if a
carry or overflow occurs. {adrs} must be within
- 32 and
+
31 of the current location.
RLA {adrs} [ , ]
Test/ Alter/Branch Skips to {adrs} if the least significant bit of the A
39
{adrs} ["
C]
register is not O. Setting or clearing the bit after the
test can be specified. {adrs} must be within - 32
and
+
31 of the current location.
RLB
{adrs} [ , =:]
Test/ Alter/Branch Skips to {adrs} if the least significant bit of the B 39
{adrs}
L

register is not O. Setting or clearing the bit after the
test can be specified. {adrs} must be within - 32
and

31 the current location.
RZA {adrs} Test/Branch Skips to {adrs} if register A isnot O. {adrs} must be
37
within - 32 and
+
31 of the current location.
RZB {adrs}
Test/Branch Skips to {adrs} if, register B is not O. {adrs} must be 37
within - 32 and
+
31 of the current location.
SAL

Shift/Rotate Shifts the A register left the indicated number of 40
bits with all vacated bit positions becoming O.
Maximum shift is 16 bits.
