NAME

       SETUSV - sets the value of one of the internal parameters of SPPS.

SYNOPSIS

       CALL SETUSV (VN,IV)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_setusv (char *vn, int iv)

DESCRIPTION

       VN          (an input constant or variable of type CHARACTER) is the name of a parameter;
                   only the first two characters are meaningful.  Remember that, in FORTRAN, a
                   constant of type CHARACTER is a string of characters enclosed in apostrophes.

       IV          (an input expression of type INTEGER) is the desired new value of the
                   parameter identified by VN, as described in the following table:

                   Parameter   Description               Possible Values of IV
                   Name (VN)
                   ---------   -----------               ---------------------
                    'LS'       Axis scaling              1 = linear X, linear Y
                               ("Log Scaling" flag)      2 = linear X, log Y
                                                         3 = log X,    linear Y
                                                         4 = log X,    log Y

                    'MI'       Axis direction reversal   1 = neither X nor Y
                               ("MIrroring" flag - axis  2 = X, but not Y
                               from maximum to minimum   3 = Y, but not X
                               rather than min to max)   4 = both X and Y

                    'MU'       Metacode output Unit      2

                    'PB'       Pen-move Buffer size      2 to 50

                   Both 'LS' and 'MI' are normally set by calling the routine SET, but can be set
                   independently by calling SETUSV.

                   The parameter 'MU' is set, prior to calling OPNGKS, to change the FORTRAN
                   logical unit number to be used by GKS for metacode output.

                   The parameter 'PB' sets the size of the SPPS polyline buffer.  The value "2"
                   effectively turns buffering off.

                   Obsolete    Description
                   parameters
                   ----------  -----------
                    'XF'       X axis exponent for plotter coordinates
                               (The PAU range would be 1 to 2**XF - 1 in X)
                    'YF'       Y axis exponent for plotter coordinates
                               (The PAU range would be 1 to 2**YF - 1 in Y)
                    'IR'       Red color intensity (relative to green and blue)
                    'IG'       Green color intensity (relative to red and blue)
                    'IB'       Blue color intensity (relative to red and green)
                    'IM'       Maximum color index to be used
                    'IN'       Overall color intensity
                    'II'       Restore color index
                    'LW'       Line width scale factor in thousandths
                               (2000 means double the default line width)
                    'MS'       Marker size in thousandths
                               (2000 means double the default marker size)

                   The values of the parameters 'XF' and 'YF' are the same as the values of the
                   arguments IX and IY in calls to the routines SETI and GETSI.

                   The parameters 'IR', 'IG', 'IB', 'IM', 'IN', and 'II' were all part of a
                   color-setting scheme meant to allow overall intensity to be set independently
                   of color.  This scheme is now obsolete; it has been replaced by normal GKS
                   color setting through the routines GSCR, GSPLCI, GSFACI, GSPMCI, and GSTXCI.
                   The corresponding GKS inquiry routines to determine current color settings are
                   GQCR, GQPLCI, GQFACI, GQPMCI, and GQTXCI.  See Section 6 of "User's Guide for
                   NCAR GKS-0A Graphics."

                   The parameter 'LW' is replaced by the GKS line width scale factor routine,
                   GSLWSC, which has the corresponding query function GQLWSC.

                   The parameter 'MS' is replaced by the GKS marker size scale factor routine,
                   GSMKSC, which has the corresponding query function GQMKSC.
