A aaa
INCB
The Increment Binary instruction
increments a binary value in a specified
V--memory location by “1” each time the
instruction is executed.
Operand Data Type DL105 Range
A aaa
V--memory V All (See page 4--29)
Discrete Bit Flags Description
SP63 on when the result of the instruction causes the value in the accumulator
to be zero.
NOTE: The status flags are only valid until another instruction that uses the same
flags is executed.
In the following example when C5 is on, the binary value in V2000 is increased by 1.
