You should be calling DmResizeRecord in that case (remember to check
for the success/failure of the resize). Maybe the pack/unpack
routines are doing that already, but it doesn't appear to be
happening in the code fragment you posted. I have found it helpful
to use a second function to compute the size of a record--especially
when I have some fields that might or might not be used.
