The following diagram shows the scan-by-scan results of the execution for our example
program. Notice how the pointer automatically cycles from 0 to 6, and then starts over at 1
instead of 0. Also, notice how SP56 is affected by the execution. Although our example does
not show it, we are assuming that there is another part of the program that changes the value in
V1500 (data source) prior to the execution of the STT instruction. This is not required, but it
makes it easier to see how the data source is copied into the table.
