APP_NAME

#define APP_NAME   "\nnanoForth 2.2 "

N4_API_SZ

#define N4_API_SZ   8

@Note 1: N4_API_SZ defines C funcion pointer slots which take 2 bytes each The number can be increased if more interfaces are needed @Note 2: TRC_LEVEL set tracing level 0 - no tracing, N4Asm::see, N4Asm::trace, and N4VM::_dump 1 - detailed tracing info of the above 2 - add execution tracing, N4VM::_nest (slower) The above codes takes extra 1.8K bytes which can be disabled if extra program memory is needed C API func ptr slots
