D+(N–1) must be less than the largest block number provided by the File
Memory Unit (0999 or 1999).
When the execution condition is OFF, FILW(43) is not executed. When the
execution condition is ON, FILW(43) transfers the designated number of
blocks (N) from the designated PC memory area starting at S, to the File
Memory beginning at D. The data is transferred in 128-word blocks.
If the last block of the source transfer area does not have a full 128 words,
the unused words of the File Memory block will be empty.
