Option 2: REPLACE IT means that the application will replace the existing program in RAM with its
own version. If the application later exits normally, it will also automatically remove its own version from
RAM so that nothing remains.
Option 3: REPLACE ALL is the same as Option 2, except that the application will automatically replace
any other programs that it uses (in those cases where it uses more than one) if duplicates exist in RAM. This
simply keeps the application from presenting the menu to you multiple times.
Option 4: EXIT THIS APP exits the application without changing RAM in any way. You may want to
select this option in order to explore what is in the existing program.
How the application differs from the previous stand-alone programs
There is one noticeable difference between the stand-alone versions of the activity programs and the
versions built into the application. Many of the stand-alone programs display a graph and quit. The user can
view the graph and then sometimes go into TRACE mode to move along the graphed function.
In the application, when the graph is drawn you are automatically put into Trace mode. After tracing, you
should press the Í key to continue running the program. This change was necessary so that you would
not have to repeatedly re-start the application. Some of the descriptions in the activity book are written
assuming the behavior is that of the stand-alone program. Whenever the activity requires tracing, you
should wait until the application automatically puts you in TRACE mode to do that part of the activity. If
you need to TRACE later, you can do this by exiting the application, pressing s to display the last
graph, and pressing r to enter TRACE mode, which will still be functional.
