And Here's where I'm really lost:

? If s1 does NOT contain maxpopaccts?
> if ((s2 = strtok(NULL, TOKENS)) == NULL)
? if the next token of NULL is null loop? (I haven't looked up continue yet,
but I assume its to restart the while.. but that's not a source of confusion yet ;)

I can usually figure this stuff out with google, and some common sense, but this
time I don't get it. Sorry about the double post.
