(T=Z;Z=Y;Y=X) X = [output ii]
(Read back an output)
Pushes the state of the nominated output number ii to X in Boolean form. Note that the value returned is the value that has been most recently set on the output by an On, Off, Output or OutputM instruction, as opposed to being a readback of the voltage at the output pin. This is particularly significant on SPLat boards with bidirectional I/O points, such as the OEM36.
* This instruction can also use the Index Register by adding i in front of the instruction.
This instruction will not read back an output ON condition resulting from an
Dialect restriction: The InputO instruction is not implemented in boards with dialect numbers less than 3.
