Chapter 6. The Obix developer console
	Part I. How to create and execute code

In addition to executing an operating system command as described in the previous chapters, you can also use the Obix developer console to execute commands. The Obix developer console is similar to a text terminal window of your operating system, but it is managed by Obix and you can only enter commands understood by Obix. The advantage is that you launch Obix only once, and then enter any number of commands, which results in faster execution. To work in a developer console proceed as follows:

Open a console by calling Obix with console as command line argument, e.g.
```
on Linux type:
./obix.sh console

on Windows type:
obix console
```
When prompted to enter a command, enter any valid command, such as one of those described in the previous chapters:
For example, to execute an instruction on Windows type:
```
ei "system.console.write_line ( \"Hello world\" )"
```
To evaluate an expression, type:
```
ev "123 + 321"
```
