Line 1: Marker state M500 is loaded into the Logic Accumulator.
Line 2: The Logic Accumulator is gated with Marker M501.
Line 3: Open parentheses: the Accumulator contents are buffered on the Program Stack.
Line 4: Input state I0 is loaded into the Logic Accumulator.
Line 5: The Logic Accumulator is gated with Input I1.
Line 6: Close parentheses: Accumulator content is gated with the content of the Program Stack,
according to the command (A[, O[, NO[ ...).
Line 7:
Note:
The result of the complete logical process is assigned to Output O12.
The functional sequence is in principle the same for word execution, with the exception that the
whole Accumulator is written onto the Stack.
