Is it possible to assign many pins to one variable?

Syncmaster:
So I just started to use an LCD S3O1C3TR which is has a small 3-digit display. Is there any way I can assign 'x' amount of pins (from my arduino) to ONE variable and then send a signal to that variable which in turn sends a signal to all the pins it was assigned under?

Sort of but not really since you don't "send a signal to a variable". You can assign values to a variable, but signals are what you send to pins.

yourVariable =
pinsOfInterest[] = {3, 5, 6, 8, 11, etc}

for (byte i = 0; i < ; i++)
doTheThing (pinsOfInterest[ i ], yourVariable, etc);

will keep writing whatever yourVariable is to all of those pins.
