digitalWrite equivilent

I'm porting a program from the Arduino to the mbed... Arduino has a function called digitalWrite and is called like:

digitalWrite(pin,HIGH/LOW);

This is actually very convenient when writing out data to multiple pins inside a loop.

Is there a way I can address a DigitalOut pin in code by pin# like this rather than by a given pin name?

thanks

Two solutions come to mind.

1. Use a BusOut or PortOut to set multiple pins at once.
2. Make an array of DigitalOut instances.

BusOut looks handy.. but would you be so kind to give an example of how you'd create an array of DigitalOut's?

Something like this: 

DigitalOut mypins[] = {p5, p6, p7};
