Hello Newsgroup,


I trying to program an interpreter in stack machine behavior.
It works fine at now - IF ELSE ENDIF FOR loops and
variable definitions like "b0 = 100".
But now, I reached the point where parameters of functions
should be interpreted. I don't know how it possible.
I pushed parameters on stack of functions that are fixed and
know by me - but how works with unknow procedure
parameters?


Here a little code snippet of the parsed interpreter code:


enter main
    npush 10
    vpush b0
    add
    nassign b0
    call @test
    ret


Thank you for helping messages
