Hi,
Well, it changes *something*, otherwise ... :)
Maybe "This is only a re-factoring."
It only moves the code section

I am all for extracting the functionality in a function,
what bothers me a little is the above construct.
Maybe you can find a more "standard: approach like:
while (recid != 0xffff) {
...
}
Or maybe is just me.
