This instruction loads data into a sequencer load file. The source of this data
can be an I/O or storage word address, a file address, or a program constant.
Entering Parameters
•
File – This is the address of the sequencer file where the source data is
loaded into. You must use the file indicator # for this address.
•
Source – This can be a word address, file address, or a program constant
(–32768 to 32767) indicating the value or location whose contents are
loaded into the sequencer file. For input addresses, the HHT requires that
you enter the slot and word number. For example, I:3.0.
If the source is a file address, its file length will be equal to the length of
the sequencer load file (LENGTH). The two files will track
automatically, per the position value.
•
Control – This is a control file address. The status bits, length value, and
position value are stored in this element. Do not use the control file
address for any other instruction.
