Maybe I am wrong but after I ran the following code:

? TRANSFORM(-16777216,"@0")

I got:
**********
not 0xFF000000

Do you have any thoughts on that?

Thanks,
Ali

>Sure it did. You're asking for 0xff to be shifted left 24 bits. If you look at the result (0xff000000) that is exactly what you got with the value of -16777216.
