TRANSCOD
Type: Adverb  (String*14)
Use:  A character string specifying the type of transposition
      desired.  The string can contain up to 14 characters,
      but it must be left justified with no imbedded blanks.
      The string may contain only the characters -, 1, 2, 3,
      4, 5, 6, and 7.  The string specifies the output axis
      sequence in units of the input axis sequence.  Thus,
      '7654321' completely reverses the order of the axes
      but keeps the pixel ordering within each axis unchanged.
      TRANCOD = '31-2' would transpose a LL - MM - VEL image
      to a VEL - LL - MM image with the highest declinations
      (MM) occurring before the lowest ones.
Null value:  '          '
      Null value means (for TRANS) to maintain the pixel and
      axis ordering of the input image.  In this case, TRANS
      becomes equivalent to SUBIM.
Tasks:
  TRANS.......A general matrix transposition task with
              subimaging and axis reversal.
