Thanks!
Yes, there were problems with the "nested" _asm keywords ( _asm { _asm nop } ), the assembler expression evaluator, and the fact that the C variable sometimes was too "dominating" in the expression (it's size).
I want this to work too, and the size should be deduced from the C variable:
_asm cmp [i],-1
It should work in 3.00 Beta 2 - which will be upload maybe tomorrow...
