Re: [FLASH-USERS] - eint_switch

Nasser -

Answering your question is not possible given the information you
provided. The first step towards providing such answer is to work with
your problem, trace code execution, and find a place where the bad
values of unk(ieint) are create. This will tell more about the input
data used to calculate unk(ieint) and possible reason for the failure.
