- Lab 2:
  - For this lab you will need to create a new option tree called `TRAIN` and add the macro you created in Lab 1 to that option tree.
    - If you have forgotten how to create an option tree, please refer back to the module on Option Trees.
    - You can just copy the file you created in Lab 1 to the `mcr` directory and then use `UPDATE` to add it to the command dictionary (you do not need to provide default values for the macro).
  - When you are done you should be able to do this:

        nM> mcrlab1 FEET=5 INCHES=6 NAME="Lee"
        INFO: Lee is 167cm tall [MCRLAB1]
