Thanks! That TextEdit works great. Super.

Now I have my next problem.
It helped a bit to do the changes mentioned above but now I get this:

My Arduino App Says:
core.a(main.cpp.o): In function main': /Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/cores/arduino/main.cpp:11: undefined reference to setup'
/Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/cores/arduino/main.cpp:14: undefined reference to `loop'

Any idea what this means?
