5-14 Data Handling Instructions
All elements are copied from the source file into the destination file each time
the instruction is executed. Elements are copied in ascending order.
If your destination file type is a timer, counter, or control file, be sure that the
source words corresponding to the status words of your destination file
contains zeros.
Be sure that you accurately specify the starting address and length of the data
block you are copying. The instruction will not write over a file boundary (such
as between files N16 and N17) at the destination. An error occurs if a write is
attempted over a file boundary.
You can perform file shifts by specifying a source element address one or
more elements greater than the destination element address within the same
file. This shifts data to lower element addresses.
Using FLL
This instruction loads elements of a file with either a program constant or
value from an element address.
The instruction fills the words of a file with a source value. It uses no status
bits. If you need an enable bit, program a parallel output that uses a storage
address. The following figure shows how file instruction data is manipulated.
