                            OBSDES DOCUMENTATION


    OBSDES compares a horizontal Blue Book Description data set  with its
respective Blue Book Observation data set .  OBSDES produces a list of error
messages along with the description data set record and observation data set
information.  The description data set may be a D-file, a unified description
data set or a old format description data set.  End of file messages may                         
precede the error messages and a summary of all observation data set control 
point record SSN's and station names for which a description or recovery note 
was not found may follow the error messages.


    It is assumed that the observation data set and description data set
have been successfully run through NEWCHKOB and CHKDES respectively and all
syntax and structure errors have been resolved.
