Arduino Due with BCD-Decoder

Hello Arduino forum!

I have a question to the BCD-Code.
I have an Arduino Due connected with an BCD-Decoder. It is possible to define a variable (e.g. "1") as 4 digital pins (10-13)?

I would like to do this, because so i can say:

"DigitalWrite(1, HIGH);

After this order order the Output of the arduino on the pins 10-13 should be like this:

0001

How can I solve this problem?
(I hope my English is good enough)

Variable names cannot start with a number but you can give pins meaningful names

byte bit0 = 13;
byte bit1 = 12;
byte bit2 = 11;
byte bit3 = 10;

void setup() 
{
  pinMode(bit0, OUTPUT);
  digitalWrite(bit0, HIGH);
}

void loop() 
{
}
