## Commentary

The following line numbers in the code perform these functions:

- Line 10 loads the `mminsight` package.
- Line 104 now contains a call to `insightmaximize` instead of `maximize`.
- Lines 109-116 contain the `LOAD` mode code.
- Lines 118-126 contain the `RUN` mode code.
- Lines 128-136 are executed when the code is executed outside Insight.
- Line 139 calls the procedure that matches the selected execution mode.
