Quick question on syntax

Hey guys:

Here’s the dilemna, I have a bunch of lines like the following:

c1.move();
c2.move();
c3.move();
c4.move();

Where c(1-4) are variables. I tried making a for() loop that simplifies everything:

for (temp = 1; temp < 5; temp++) {
	('c'+temp).move();
}

The problem is that I can’t get (‘c’+temp) to equal the variable named c1 (or c(2-4) for that matter). How do you do this?
