SOURCES
Type: Adverb  (String*16, 30 elements)
Use:  Standard data selection adverb, used to specify a list of source
      names to be included in or excluded from an operation.  If the
      first character of ANY element is "-" then all named sources are
      excluded else all named are included.  All must be left justified.
      All blanks mean all sources are selected.  Note that some tasks
      do not have the exclusion option and some tasks use only
      SOURCES(1).
Null Value:  '                '

      after a non null value are ignored.
