ORA-06502 behaves different way in 10g forms and 6i

Question

If To_Number(Figc1) <> 0 Then
Figword := CVT(Figc1);
Figword := Figword || 'MILLION ';
End if;
This is a code from Report Builder 6 procedure . Here Figc1 variable contains three spaces ' ' . but it does not fire any exception when it converts to number. But when i run this in 10g application server. it throws 06502 error message..
I have alot of RDF files which i migrated from 6i to 10g. many reports containing same code . So do i have to change all reports or please let me know whats the reason of this error message.....

Well as said I would consider this as a bug you introduced which needs to be corrected wheter this worked previously or not. A string containing blanks and a number is a string with blanks and a number, not a number. At least in my book. If you have many reports containing such constructs you could convert them to a XML file with rwconverter, change your code in batch by a program written in whateverelse and convert it back to a .rdf file afterwards. This would be my preferred solution as changing the environment would only affect your server, there is no guarantee that after some time you'd need to setup another one, and what exactly was the setting which needed to be made to get your reports running...? Let alone what happens when migrating to 11g as you might hit the same problem which isn't corrected by your hack in newer versions.
This is what I'd do, maybe someone else has a better idea.
