Compilation of large record cause the incorrect result ?

Hi all,

Is it huge and complexity calculation of record will influence the result of compiling huge large records? I got one program wrote by my ex-colleague, the program need compare pass year record everytime for calculation and display result. I'm using same version of exe for display the result, but the system display inconsistant data either incorrect or correct.
Any comment of this..

Thanks a million

If it truly is the amount of data, then maybe try posting your code so we can point out some sort of inconsistency?
