  Illegal or illogical access (ERR=136)

  The requested access is impossible because:

   o  The attempted record operation and the ACCESS clause in  the  OPEN
      statement are incompatible.
   o  The ACCESS clause is inconsistent with the file organization.
   o  ACCESS READ or APPEND was specified when the file was created.

  Change the ACCESS clause.
