HELP SECTION

DEFER
Type: Adverb (Real)
Use:  Controls when someoperation such as file creation is actually
      done.  Normally, AIPS tasks create all output files at the
      beginning along with any needed scratch files.  This insures
      that adequate disk space is available.  However, when it is not,
      it is sometimes possible to reduce the overall disk requirement
      of a task by deferring some of the file creation until some of
      the scratch files may be deleted.
Tasks:
   UVSRT.....Sort a UV dataset into a specified order
             DEFER > 0 specifies that the output file is created only
             after one of the two scratch files may be deleted.
