- Lab 1:
  - This lab will introduce you to using commands in other option trees.
  - For this lab you will need to add two option trees to your path:
    - The UCL option tree to your path (hint: use `OPTION` to see if it is already defined).
    - The SAMPLEOPT option tree (version 1.2.3). You will need to save either the `.zip` or the `.tar.gz` file to your local disk (both are identical) and uncompress it. Once you've uncompressed it use the `OPTION` command to tell NeXtMidas where it is located.
      - sampleopt123.tar.gz (Unix)
      - sampleopt123.zip (Windows)
      Notes:
      - The SAMPLEOPT option tree contains only macros and does not need to be compiled.
      - You can save the `.tar.gz` or `.zip` file in your home directory and expand it there. Then use the `OPTION` command to add the necessary link.
  - Once you've added those option trees, please answer the following questions:
    1. What is the name of the switch for the `KAISWIND` command (in DSP) that indicates that "Output response should be complex"?

    2. When you run the `DEMO` command in the SAMPLEOPT option tree, what is plotted?

    3. You now have two `DEMO` commands available (one in SAMPLEOPT, the other in SYS). Which one runs when you just type `DEMO`? Can you run the other one? If so, how?

    4. How do you change your homepath to be the `mcr` area of SAMPLEOPT?

    5. How do you change your OS's working directory to the `mcr` area of SAMPLEOPT?
