### ASM_PROGRAM_VARIABLE

This program prints Hello, World! to the console.

#### Building

Perform the following commands to compile the project:

```
username@host:~$ cd agon-development/ASM_PROGRAM_VARIABLE/asm
username@host:~$ make
Building project...
mkdir -p bin
ez80asm -x src/main.asm
Assembling src/main.asm
Pass 1...

```

#### Running the program

The newly built program can be run within the Fab Emulator using the following commands:

```
username@host:~$ make run
```

This will launch the Fab emulator.  Once the emulator has started check the binary is accessible to the emulator by using the dir command:

```
/ *dir
Volume: hostfs
Directory: /

ASM_PROGRAM_VARIABLE.bin
```

Then run the binary using by loading it and issuing the run command:

```
/ * load ASM_PROGRAM_VARIABLE.bin
/ * run
Hello, World!
```
