# Getting started
|
||
|
||
## Hello world example
|
||
|
||
Save the following as `hello_world.mfk`:
|
||
|
||
```
|
||
import stdio
|
||
|
||
array hello_world = "hello world" petscii
|
||
|
||
void main(){
|
||
putstr(hello_world, hello_world.length)
|
||
while(true){}
|
||
}
|
||
```
|
||
|
||
Compile is using the following commandline:
|
||
|
||
```
|
||
java millfork.jar hello_world.mfk -o hello_world -t c64 -I path_to_millfork\include
|
||
```
|
||
|
||
Run the output executable (here using the VICE emulator):
|
||
|
||
```
|
||
x64 hello_world.prg
|
||
```
|
||
|
||
## Basic commandline usage
|
||
|
||
The following options are crucial when compiling your sources:
|
||
|
||
* `-o FILENAME` – specifies the base name for your output file, an appropriate file extension will be appended (`prg` for Commodore, `xex` for Atari, `asm` for assembly output, `lbl` for label file)
|
||
|
||
* `-I DIR;DIR;DIR;...` – specifies the paths to directories with modules to include.
|
||
|
||
* `-t PLATFORM` – specifies the target platform (`c64` is the default). Each platform is defined in an `.ini` file in the include directory. For the list of supported platforms, see [Supported platforms](../target-platforms.md)
|
||
|
||
You may be also interested in the following:
|
||
|
||
* `-O`, `-O2`, `-O3` – enable optimization (various levels)
|
||
|
||
* `--detailed-flow` – use more resource-consuming but more precise flow analysis engine for better optimization
|
||
|
||
* `-s` – additionally generate assembly output
|
||
|
||
* `-g` – additionally generate a label file, in format compatible with VICE emulator
|
||
|
||
* `-r PROGRAM` – automatically launch given program after successful compilation
|
||
|
||
* `-Wall` – enable all warnings
|
||
|
||
* `--help` – list all commandline options |
