Here is the whole thing, and it compiles without errors for me.

byte relay_address1;

void setup(){
Serial.begin(9600);
}
 
void loop(){
Serial.print(relay_address1, BYTE);        // send relay module address
Serial.print(100, BYTE);          // All relays on
 
Serial.print(relay_address1, BYTE);        // send relay module address
Serial.print(101, BYTE);          // Turn relay 1 on
 
//etc
 
Serial.print(relay_address1, BYTE);        // send relay module address
Serial.print(110, BYTE);    //All relays off
 
Serial.print(relay_address1, BYTE);        // send relay module address
Serial.print(111, BYTE);    //Turn relay 1 off
//etc
}
