Description:

SUBROUTINE GRMARK (IDENT,CENTER,SYMBOL,ABSXY,POINTS,X,Y)

GRPCKG: mark a sequence of points with a specified symbol. The
plot is windowed in the current subarea.

Arguments:

IDENT (integer, input): plot identifier from GROPEN.
CENTER (input, logical): if .TRUE. the symbol is centered on the point,
otherwise the bottom left corner is placed at the point.
SYMBOL (byte or integer, input): code number of symbol in range 0-127
(ASCII character or special symbol); if SYMBOL is outside this
range, nothing is plotted.
ABSXY (logical, input): if .TRUE. (X,Y) are absolute (device)
coordinates; otherwise they are world coordinates and the
scaling transformation is applied.
POINTS (integer, input): the number of points; if POINTS is less than
or equal to 0, nothing is plotted.
X,Y (real arrays, dimension at least POINTS, input): the coordinate
pairs; if POINTS=1, these may be scalars instead of arrays.
