What is wrong with this Script logic?

Didn't something change recently with the recursion limit? Maybe
something in the engine changed too. Also, I've had a few cases where
inserting a breakpoint changed the way the handler behaves, which makes
me think in this case the debugger is managing the recursion somehow.
I'm just guessing.
Mostly what I wanted to say is that usually I avoid the whole issue like
on hCheckEntry pData
repeat until pData is an integer
ask warning "Please enter only whole numbers!" with pData \
titled "Enter A Number"
if the result = "cancel" then exit to top
put it into pData
put pData into me
