Sequencer Instructions
Chapter 15
159
the data monitor display of a sequencer instruction and a file instruction
should be noted. The Sequencer Output instruction will be used as an
example. Each column in the sequencer table represents the data for each
output word. This data controls the outputs of the corresponding output
word at each step in the sequencer operation. The status of the outputs can
be observed in the output address data displayed in the header.
In contrast, each column in a File instruction display represents a complete
file. File data is manipulated by the instruction. The result of the
instruction operation is contained in the result file or in a specified word
address of the instruction.
