We assume that instructions are unsigned numbers.

`A' : 8 bits

`C' : 9 bits

`Bx' : 18 bits (`B' and `C' together)

value is the unsigned value minus K. K is exactly the maximum value

represented by 2*max), which is half the maximum for the corresponding

Notes:
|

(*) In OP_CALL, if (B == 0) then B = top. C is the number of returns - 1,
|
||||
and can be 0: OP_CALL then sets `top' to last_result+1, so
|
||||
next open instruction (OP_CALL, OP_RETURN, OP_SETLIST) may use `top'.
|
||||
|
||||
(*) In OP_VARARG, if (B == 0) then use actual number of varargs and
|
||||
set top (like in OP_CALL with C == 0).
