GCCollect doing ?, and what is the best way to use it.

I come from Blitz3D and this is something new for me.

Sample please on simple code.

You don't need to use it.
Don't worry about garbage collection. The GC will collect when it needs to.

Hi,
Deinit is that it is not necessary , the object is deleted alone?

Ah, well with pure BlitzMax code you usually don't need to worry about GC.
However, with 3rd-party libraries, you often need to clean up "foreign" objects yourself - because they are not completely managed by the GC.
Which things you need to handle yourself is different for each library you are using.
If in doubt, clean it up yourself :-)
