S+(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, FILR(42) is not executed. When the
execution condition is ON, FILR(42) reads blocks of data from the File
Memory (128-word blocks), and outputs the data to the designated PC
memory area beginning at D.
If the destination memory area is too small to accommodate all of the transfer
data, only the portion that fits will be transferred.
