It is really so that if you can read individual stream records, then it is
enough to skip first 8 By and concatenate the record leftovers.
Reading records at the PC side should not be difficult either. They have
constant length of 4104 By.
Sources of par program can be traced somewhere - they can serve as a
guidance to understanding the pdb format.
