Post your updated loop or method - enough to see the changes you made.

You can use the catch{} block to achieve this. Your code indenting is also funky, causing the code to be harder to read:
do
{
// reset the repeat flag
firstWGood = true;

try
...

If firstWord is true, then !firstWord is false, and the do/while loop will end. The sample run you posted confirmed that.

Don't question the results, question the logic that provided the results.
