TICK4 - Allows for program control of tick mark length and direction.

       To  use  TICK4  or c_tick4, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in
       that order.

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

       #include <ncarg/ncargC.h>

       void c_tick4 (int lmjx, int lmnx, int lmjy, int lmny)

       All arguments are in plotter address units (PAUs). By default, one PAU is 1/1023rd of the width of the
       plotter frame.

       Note: A call to the SPPS routine SETI will change the definition of a PAU. Such calls are no longer
       recommended, but the possibility still exists.

       LMJX and LMNX
                   (input  expressions  of type INTEGER) are the lengths, in plotter address units, of major and
                   minor ticks on the X axis. The default values are 12 and 8.

       LMJY and LMNY
                   (input expressions of type INTEGER) are the lengths, in plotter address units, of  major  and
                   minor ticks on the Y axis. The default values are 12 and 8.

       By  default, tick marks point inward. Negative values of LMJX, LMNX, LMJY, and LMNY may be used to create
       outward-pointing tick marks.

       Use the ncargex command to see the following relevant example: tgrida.
