C--                 in the MITgcm UV implementation environment.
C--   Contents
C--   o PRINT_MESSAGE  Does IO with unhighlighted header
C--   o PRINT_ERROR    Does IO with **ERROR** highlighted header
C--   o PRINT_LIST_I   Prints one-dimensional list of INTEGER
C--                    numbers.
C--   o PRINT_LIST_L   Prints one-dimensional list of LOGICAL
C--                    variables.
C--   o PRINT_LIST_RL  Prints one-dimensional list of Real(_RL)
C--                    numbers.
C--   o PRINT_MAPRS    Formats ABCD... contour map of a Real(_RS) field
C--                    Uses print_message for writing

C     |   ignored!
C     | o In a non-parallel form these routines can still be used.
C     |   to produce pretty printed output!

C     | SUBROUTINE PRINT\_MAPRS
C     | o Does textual mapping printing of a field.
C     *==========================================================*
C     | This routine does the actual formatting of the data
C     | and printing to a file. It assumes an array using the
C     | MITgcm UV indexing scheme and base index variables.
C     | User code should call an interface routine like
C     | PLOT\_FIELD\_XYRS( ... ) rather than this code directly.
C     | Text plots can be oriented XY, YZ, XZ. An orientation
C     | is specficied through the "plotMode" argument. All the
C     | plots made by a single call to this routine will use the
C     | same contour interval. The plot range (iMin,...,byStr)
C     | can be three-dimensional. A separate plot is made for
C     | each point in the plot range normal to the orientation.
C     | e.g. if the orientation is XY (plotMode = PRINT\_MAP\_XY).
C     |      kMin =1, kMax = 5 and kStr = 2 will produce three XY
C     |      plots - one for K=1, one for K=3 and one for K=5.
C     |      Each plot would have extents iMin:iMax step iStr
C     |      and jMin:jMax step jStr.

C     !DESCRIPTION:
C     *==========================================================*
C     | SUBROUTINE PRINT\_MAPRL
C     | o Does textual mapping printing of a field.
C     *==========================================================*
C     | This routine does the actual formatting of the data
C     | and printing to a file. It assumes an array using the
C     | MITgcm UV indexing scheme and base index variables.
C     | User code should call an interface routine like
C     | PLOT\_FIELD\_XYRL( ... ) rather than this code directly.
C     | Text plots can be oriented XY, YZ, XZ. An orientation
C     | is specficied through the "plotMode" argument. All the
C     | plots made by a single call to this routine will use the
C     | same contour interval. The plot range (iMin,...,byStr)
C     | can be three-dimensional. A separate plot is made for
C     | each point in the plot range normal to the orientation.
C     | e.g. if the orientation is XY (plotMode = PRINT\_MAP\_XY).
C     |      kMin =1, kMax = 5 and kStr = 2 will produce three XY
C     |      plots - one for K=1, one for K=3 and one for K=5.
C     |      Each plot would have extents iMin:iMax step iStr
C     |      and jMin:jMax step jStr.
