Re: A83: Re: How do you...


Ok...

libs: .db "ZLIB",0,0,0,0,lib2,vec0
 .db $FF

The format of the library table is:
 - first 8 characters = library file name (use zeros if the name is less
than 8 characters). "ZLIB",0,0,0,0
 - the next byte is the number of the library routine you want to access.
e.g. lib2 would be the random
        routine.
 - the last byte is the number of the vector you want to call in order to
access the library. So if you put
        vec0, when you called vector0 you would get the random routine
(lib2) for this example
- if this is the last routine you want to set up, put an $FF, otherwise
continue with the table.
Note that using lib2 and vec0 is necessary, you can't just put a 2 or
something.
