Does anyone know how to calculate the CKVAL field in a project file? I assume it's a checksum like the CKVAL in the resource file, but what's it calculated on?

In a resource file it's calculated on the DATA field, like:
REPLACE CKVAL WITH VAL(SYS(2007, SUBSTR(DATA,3)))

But the project has no DATA field, of course.

Thanks,
Chris
