If you initialised the records first using FillChar( ) it would work okay, then you
know it's all unused areas are initialised.
Is there a better way than fillChar() these days??.

or have any datatypes which are not word aligned... Note that nonpacked
records
have padding bytes that are not initialised (or at least I don't believe you
can
trust them to be initialised)...
Thus byte fields or byte arrays would be out... Comments?
