SUBROUTINE SETMS (MARKNO)
C$ (Set Marker Symbol)
C$ Set the current marker symbol number to "MARKNO". Markers
C$ always appear at a standard orientation and size --
C$ unrotated, centered at the current point, in the view
C$ surface plane, and of a size corresponding to hardware
C$ character size (about 0.01 on a scale of 0..1). Markers
C$ are not affected by world coordinate object modelling
C$ transformations or by perspective or rotation.
C$
C$ Markers 1-5 are standard in all CORE implementations. The
C$ remaining ones are implementation-dependent. Markers
C$ currently supported are taken from the Hershey font
C$ digitizations. The Hershey numbers are given in
C$ parentheses below for each marker. Marker heights have
C$ been adjusted to make them all roughly the same size.
