I don't know if it would make a difference (it is hard to see
how it could, actually) , but the PalmOS API has it's own
even when it comes to the standard variable types.
Perhaps you should use "const Char *s" (note the capital
'C') as your parameter prototype.

Do you have any code before the line
containing "UInt index = ..."?
One of the things that loosened up in C++ was
the ability to declare variables, have some code,
then declare more variables. In C however this
is still not ok. All declarations must occur at the
beginning of a code block.
