Simple Variable Question

How do I say i = (numbers 100 through 199)?

Basically I just need to parse through some XML values. So if there is another way to say this:


//all my images are name similar; category-pic-number (ie. building-pic120.jpg)
//k would be something like what I wrote above.

if(image[p] = category+"-pic"+i+".jpg") {
       trace("this image is special");
}
