- Lab 1: This lab will introduce you to using the `AUX`, `FILES`, `STATUS`, `HEADER`, `FNAME` and `DATALIST` commands.
  - What you need to do:
    1. Use the `WAVEFORM` or `HEADER/CREATE` command to force a file called `myfile.tmp` to be created in your home directory.
    2. If it is not already on your read AUX list, put HOME on it. Now run the command:

           nM> waveform myfile.tmp ELEM=8k

       Where was the file created?
    3. Use the `FILES` command to find the name of the shape (`.shp`) file that is located in the `dat` area of SYS.
    4. Use the `STATUS` command to find out the size (number of bytes) of the shape file in the `dat` area of SYS.
    5. Use `DATALIST` to list the data in `airports.csv`.
    6. Now use `STATUS` with the `/d` switch to list the header and data in `airports.csv`. But, this time, give it the `HEADERROWS=1` qualifier, and see what happens.
    7. Set up an AUX called WEB and point it to
       original: `http://nextmidas.com/nm/nxm/sys/dat/` (currently unavailable)
       alternate: `file:///opt/midas/nxmlatest/nxm/sys/dat/` (where /opt/midas/nxmlatest is a softlink to your local nxm installation)
       Now list the header of the world.prm in this AUX.
    8. Use the `HEADER` command to create the similarly named files called `temp_xxx_file.tmp`, `temp_yyy_file.tmp`, `temp_xyx_file.tmp`, and `temp_zzy_file.tmp`. Then use the `FILES` command to find all files starting with temp_, with a y somewhere after the temp_ and ending with _file. Use the `FILES/E` command to erase all of the files you created.
    9. Use `FNAME` to form the path for the DAT area of the SYS option tree.
    10. Use `FILE` to open the `airports.csv` file, convert it into a table with a row prefix of `R_` excluding the header, then close the file. Hint: Find appropriate operation (e.g. toTable) to use on the CsvFile. See the NeXtMidas explain file for examples, FILE .
  - Hints:
    - Before using `airports.csv`, take a look at the API for the CsvFile class. It has a good explanation about the `HEADERROWS=` qualifier.
