Detect the platform, android or iOS?

I am wanting to refrain from having 2 source files for my game (ios and android) as that defeats the whole idea of cross platform and efficient development.

Admob requires to be platform specific, and has different ID's depending on the platform. Therefore I need to check which platform is being used in order to choose which ID's it uses.

How do i do this?

Note: I have seen the browser lets you "compare" the platform, but as the documentation only mentions "Win32 for windows" and nothing else its a guessing game to find out what it will return on iOS and Android?

If you're using the C2 runtime, use the System object's 'Is on platform' condition. In the C3 runtime, use the Platform Info object.

Thanks, not sure how i missed that one!
