Compile the attached as a C16 object and run under a C32 session.
Input 0-, 0.00- or just a minus sign.
You'll see that the value of the data after input and stored in a file is negative zero.
Interestingly, logical comparison treats the value as zero while a (BZ) does not.
And, as I said originally, when the value is exported to MySQL it does wreak havoc.
This behavior does not happen when run in a C16 session or when compiled as a C32 object.

That being said, PDF Systems does intend to notify all of our end-users within the next month to budget for upgrade to C32-compiled objects next year. Any end-user choosing not do do so will have a substantial increase in monthly maintenance.
