| Lab 3: This lab will ask you to do some things with tables. You may need to look at some of the explain files in order to find out how to use some of the commands. What you need to do: The NeXtMidas shell comes with a few tables pre-defined (`AUX`, `OPT`, `REG`, `RAM`, and `ENV`). What is the value of `USER` in the `ENV` table? The registry table (`REG`) has a table of handlers. The table of handlers has multiple tables in it, one of which is called `FILE`. In that `FILE` table, what is the value of `JPEG`? Set a result named `FILE_TYPE` to `PRM`. Use `SAY` to print out the value in the `FILE` table that corresponds with `FILE_TYPE`. Create an empty table called `PEOPLE`. Add two sub tables to it, the first named `JOHN` set to `{AGE=32,HEIGHT={FEET=5,INCHES=9}}` and the second named `LINDA` set to `{AGE=30,HEIGHT={FEET=5,INCHES=2}}`. Use `CALCULATOR` to compute John's total height in inches. Store that value in a result named `HEIGHT`. Compute John's total height again in inches, but this time store it back into the people table under John's entry. Call it `HEIGHT`, replacing the previous height in a table with a total height in inches. Then do the same for Linda. Use `INFO` to print out John's and Linda's heights in inches. When it prints it should look like "`John is 69.0in tall`".
