#define _TYPEMASK   0xF000  // mask for the entry type

#define _READ       0x0100  // can be read
#define _BWRITE     0x0200  // can be used as Lvalue
#define _LVALUE     _BWRITE  // can be used as Lvalue
#define _READWRITE  0x0300  // both
#define _OPT        0x0400  // TRUE: optional parameter
#define _METHOD     0x1000  // mask bit for a method
#define _PROPERTY   0x2000  // mask bit for a property
#define _COLL       0x4000  // mask bit for a collection
                            // combination of bits above:
#define _FUNCTION   0x1100  // mask for a function
#define _LFUNCTION  0x1300  // mask for a function, that works as Lvalue too
