keep getting compiler error 18 (missing bracket) for no reason!

Just started a new little project, but for some reason the compiler doesn't recognize my closing brackets! If I copy paste other code into my file it works. SOME of my own brackets he recognizes too, but I see no reason for that either... Any experiences with that, or am I making some stupid mistake?

My code so far:

#include "mbed.h"
//#include "LCD_lib.h"


DigitalOut led1(LED1);
DigitalOut led2(LED2);
DigitalOut led3(LED3);
DigitalOut led4(LED4);

DigitalOut regsel(p5);
DigitalOut r_w(p6);
DigitalOut enable(p7);


#define DB_MASK 0b100001111000000001000011

PortInOut dbport(Port0, DB_MASK);   // THIS GENERATES AN ERROR FOR A MISSING BRACKET AFTER THE D

int write(int data){
    r_w = 0;
    regsel = 0;
    
    enable = 1;
    
    wait_us(1);
    dbport = data;
    wait_us(1);
    
    enable = 1;
    return 0;
}

int check_busy(){
    r_w = 1;
    regsel = 0;
    while(dbport && 0h80 == true); // HERE AFTER THE 0h
    return 0;
}

int main() {
    wait_ms(50);
   
    while(1) {
        
        write(0b00110000); // HERE AFTER THE 0b //function set
        check_busy();
        write(0b00111000); // HERE AFTER THE 0b //function set
        check_busy();
        write(0b00001111); // HERE AFTER THE 0b //display ON OFF
        check_busy();
        write(0x01);    //Display Clear
        check_busy();
        write(0b00000110);  // HERE AFTER THE 0b
        
    }
}

Ok, I found my mistake. I did not know that the compiler doesn't like my binary numbers. Switch them nfor hexadecimal representations and everything is fine.
