Because gambas does not check integer overflow when converting from one type 
to the other. So, when you convert any integer value to a byte, only the 
lowest byte is kept. And when you convert TRUE, you get 255 because TRUE is 
stored as -1 in memory.

I don't know how to check overflow after a conversion in C, without doing slow 
supplementary tests.

Does 'Draw.Text("test1\ntest2", 100, 100)' work ?
