PROJECT      string   // main name of program
OBJECT_KEY   string   // prefix key for objects
MAX_KEY      num      // maximum attribute number
MAX_OBJECT   num      // maximum object number
MAGIC_NUMBER num      // server version (see magic.lst)

@CONST, @VALUE, @DOCU; // constants

TYPE can be:

        int,char,double,float

        dllh            header of DoubledLinkedList
        aisc_string     string
        bytestring      string

        // [func    function ]

        or any user defined type

        Note: when using aisc_string as result type of a callback (i.e. %), you have to
              store it in some static buffer and return aisc_cstring!

REF can be:
        %               virtual (aka callback)

                        unspecified ( double char .... )
eor     i               or owner by insertion
eor     o               owner by pointer
eor     d               special owner (double linked list with ident + hash)
eor     l               link
eor     r               reversed_link   (only to those objects with dllh)

        e               enum type
eor     t               terminal type
eor     s               structure type  /* unfold THIS structure else t */

[       *               resizeable vector of ...        (key SIZE is size)
eor     v               fixed   vector of ...           (key SIZE is size)]

[       f               forward reference                               ]
                                                        (THIS-> is father)

z.B.    os*     Vector of unfold substructures


ACC             Accessiongrants
        ,       read and write
        r,      readonly
        w,      writeonly
        c,      createonly
        rw,     read and write
        privat,
        public,

SAVE    version number for load/save (if AISC_SAVE=YES)

KEY     key name

KEYC    key number

        Has to be unique inside each STRUCT.
        Keys w/o keynumbers exist, but are not accessible via interface.
        Several types use multiple KEYs (e.g. 'd' uses 2 keys (KEY and KEY+1)).

INIT    default value or call to init-funtion
        'THIS' is replaced by pointer to STRUCT
