In the following increment example, when C5 makes an Off-to-On transition the value in
V1400 increases by one.
In the following decrement example, when C5 makes an Off-to-On transition the value in
V1400 is decreased by one.

Increment (INC)
The Increment instruction increments a BCD value in a
specified V-memory location by “1” each time the instruction
is executed.
Decrement (DEC)
The Decrement instruction decrements a BCD value in a
specified V-memory location by “1” each time the instruction
is executed.
