Problem with macro names

#define I2Ca...(0x27) //I2C adress, you should use the code to scan the adress first (0x27) here
#define(BACKLIGHT_Pin)...(3); // Declaring LCD Pins
#define(En9)...(2);
#define(Rw8)...(1);
#define(Rs7)...(0);
#define(D4)...(4);
#define(D5)...(5);
#define(D6)...(6);
#define(D7)...(7);

error : macro names must be identifiers

(What’s) (with) (all) (the) (parentheses) (and) …(ellipsis)?
And semicolons?
