There is no existing compiler for all this programming language any more. Maybe someone will give it a try and create an interpreter.

There are plenty: https://en.wikipedia.org/wiki/Z-machine https://en.wikipedia.org/wiki/Z-machine

  Z-Machines aren't compilers, they're virtual machines that can execute the compiled output. There's no (known) compiler that still exists that can compile ZIL into Z-code. edit: except for zilf, as mentioned, but it's not functional for even zork 1.

    Not functional? Warnings aren't errors. Maybe it's just better at catching potential bugs...

    judging from the blog comment it seems that it's functional

    ZILF works just fine. There's even a competition for games written in ZIL using it: https://www.facebook.com/groups/ZILcom/permalink/767016233740109/ https://www.facebook.com/groups/ZILcom/permalink/76701623374...

  you mean interpreters, but this is about compilers of which there are only two: Zilch en ZILF.

  Looking at the code, it seems doable to make sense of it, one instruction at a time. For example this: "Would you like to restart the game from the beginning, restore a saved game position, or end this session of the game?| (Type RESTART, RESTORE, or QUIT):| >"> <READ ,P-INBUF ,P-LEXV> <SET WRD <GET ,P-LEXV 1>> <COND (<EQUAL? .WRD ,W?RESTART> <RESTART> <TELL "Failed." CR>) (<EQUAL? .WRD ,W?RESTORE> <COND (<RESTORE> <TELL "Ok." CR>) (T <TELL "Failed." CR>)>) (<EQUAL? .WRD ,W?QUIT ,W?Q> <QUIT>)>>> - Read user input, and put result in WRD - Switch statement on WRD - Case RESTART: Write Failed and restart - Case RESTORE: Write Ok and continue - Case QUIT: Write Failed and exit

    I looked at the zork code. Does it reference (missing?) external files, like ADVSAVE ?
