Civileme, Carroll, Kirby... thanks. Ya know, it actually makes sense. I understood
the concept of the for loop, but the rest was without meaning to me,
especially .+ .+. And gawk... sounds like someone is choking.
Thanks for taking care of us lower on the food chain. <g>

"The way I see it, there were two great triumphs, two things that I'm proudest of. One
is the economic recovery, in which the people of America created - and filled - 19
million new jobs. The other is the recovery of our morale. America is respected again
in the world and looked to for leadership."
