WARNING: The counter address for the word-to-file move and
file-to-word move instructions should be used only for the intended
instruction and the corresponding instructions which manipulate the
accumulated value. Do not inadvertently manipulate the preset or
accumulated word. Changes to these values could result in
unpredictable machine operation or a run time error. Damage to
equipment and/or injury to personnel could occur.
There are three sequencer instructions:
Sequencer input
Sequencer output
Sequencer load
These instructions either transfer information from the data table to output word
addresses, compares I/O word information with information stored in tables, or
transfers I/o word information into the data table. Understanding and applying
these concepts will give you flexibility with your programs.
Refer to Figure 6.13 while you are reading about each sequence instruction.
