Wip: implement Grass (Ueno, 2006) without pushing global and local values to data stack

How I want to implement Data

Each data is represented as unsigned integer. 0-255 as such Byte, 256 as I, 257 as K, 258 as KI, 259 as read, 260 as next, 261 as out, n>=262 if n is even as N-th code, else n is odd as N-th previous item on data stack.

Alternative

n>=262 where

Idea of compiling Grass esolang
T is unsigned integers type
Program ::= /* */ | Program Cmd
Var = Local T | Param T | Globl T | Wtf
App = [2]Var
Abs = struct { args: T; len: T; body: [len]App; }
Cmd = App | Abs
In var union, T indicates 0-indexed variable index
