Internally indexed file instruction
Complete Mode of Operation
In the complete mode, the rate per scan is equal to the file length value and
the entire file is operated upon in one scan.
For each false-to-true transition of the rung condition, the instruction is
enabled and the accumulated value of the file counter is internally indexed
from the first to the last word of the file. As the accumulated value points
to each word, the operation defined by the file instruction is performed.
After the instruction has operated on the last word, the done bit (bit 15)
is set.
