Macros
#define	APP_NAME "eForth1 v2.6"

#define	OPCODES

Capacity and Sizing
Attention reassemble ROM needed if FORTH_TIB_SZ or FORTH_PAD_SZ changed
#define	CELLSZ 2

#define	CFUNC_MAX 8

#define	FORTH_ROM_SZ 0x2000

#define	FORTH_UVAR_SZ 0x20

#define	FORTH_DIC_SZ (0x400-FORTH_UVAR_SZ)

#define	FORTH_STACK_SZ 0x80

#define	FORTH_TIB_SZ 0x80

#define	FORTH_RAM_SZ

Memory Map Addressing
note: Forth only needs a few bytes for Arduino auto (on heap), but Serial default TX/RX buffers uses 0x40 * 2 = 128 bytes logic and stack op macros (processor dependent)
#define	FORTH_BOOT_ADDR 0x0000

#define	FORTH_RAM_ADDR FORTH_ROM_SZ

#define	FORTH_UVAR_ADDR FORTH_RAM_ADDR

#define	FORTH_DIC_ADDR (FORTH_UVAR_ADDR + FORTH_UVAR_SZ)

#define	FORTH_STACK_ADDR (FORTH_DIC_ADDR + FORTH_DIC_SZ)

#define	FORTH_STACK_TOP (FORTH_STACK_ADDR + FORTH_STACK_SZ)

#define	FORTH_TIB_ADDR (FORTH_STACK_TOP)

#define	FORTH_MAX_ADDR (FORTH_TIB_ADDR + FORTH_TIB_SZ)

Logical
TRUE cannot use 1 because NOT(ffff)==0 while NOT(1)==ffff which does not need boolean op (i.e. in C)
#define	TRUE -1

#define	FALSE 0

VM operational flags
#define	fCOLON16 0x8000

#define	fCOLON8 0x80
