HELP SECTION

PUTTHEAD
Type: Verb
Use:  PUTTHEAD is used to alter the contents of a keyword/value pair
      in a table header.   A limited number of new keywords may be
      added.
Adverbs:
  INNAME......Image name(name).   Standard defaults.
  INCLASS.....Image name(class).  Standard defaults.
  INSEQ.......Image name(seq. #).  0 => highest.
  INDISK......Disk drive # of image.  0 => any
  INEXT.......Table type.  No defaults.
  INVERS......Table version #.  0 => highest.
  KEYWORD.....The FITS name of the parameter.  No default.
  KEYVALUE....The value to be given to an integer parameter if
              KEYVALUE(1) and to a floating-point parameter is
              KEYVALUE(1) + KEYVALUE(2).  No default.
  KEYSTRNG....The value to be given to a character parameter.
              No default.  If the first character is 'T', a logical
              parameter will be treated as true.
  KEYTYPE.....If a keyword is to be added to a catalog header then the
              data type of the associated value must be specified.
              The values 'D', C', 'I', and 'L' correspond to double
              precision (used for all floating-point values),
              character (up to 8 characters), integer and logical.
  DOHIST......If < -1.5, the transaction will not be recorded in the
              history file.  Otherwise the previous and new header
              values are put in the history file since this is a
              potentially important operation.
