I'm currently trying to do a line-by-line transcription of a CPU emulator that somebody's been misguided enough to write in JavaScript.

In case of arrays you can already do the following: === code begin === const NullMemMod: array[0..7] of Pointer(* or whatever *) = (Nil, Nil, Nil, Nil, Nil, Nil, Nil, Nil); // somewhere else: Self.MemMod := NullMemMod; === code end === Regards, Sven
