Read the docs on 'binding synchronization'. WO automatically moves the
bound values in both directions ensuring the correct value is in the
correct place at the correct time.

If I can't do functions with arguments, I could have a class

int currentLane;
int getSpeed() {
return(speed[currentLane]);

But then how do I wrap the WOString in something which allows me to
set the currentLane variable for the particular cell?
A WORepetition has an "index" key that can be bound to your
"currentLane" instance variable (0- not 1-based). Then with your
WOStrings' value keys bound to "getSpeed", your cells should be
appropriately populated.
I see how to communicate from my table cell back to the page component
using WORepetition using the index key.
Is there a component which does this in a more general way? In other
words, is there some way to have a component (table cell, WOString,
whatever) set values in the page component? It seems very easy to
pull values from the page component for use in the subcomponent but I
can't see anyway to pass information the other way. Except for a
couple of specialized cases like the index in WORepetition.
