im writing a free tool for SEO... implementing an api from seomoz and the flags look like this

URL Metric,Bit Flag
Title,1
URL,4
Subdomain,8
Root Domain,16
External Links,32
Links,2048
mozRank,16384
mozTrust,131072

these are just a few but i dont know how to calculate the proper bit flag in javascript... is it just an OR of all the integers of the flags i want to use? a small snippet to show me how to make a var that holds some of these flags would be awesome...

thanks for your help!

Just like in C:

var flags = 0;
// *snip*
flags |= MyFlag;
flags |= MyOtherFlag;
// *snip*
if ((flags & MyFlag) == MyFlag)
{
    // do stuff
}

is it just an OR of all the integers of the flags i want to use?

Yes. Title|URL|Links (etc.) would be 1|4|2048
