The GSET('MARREP',
. . . ) function assigns a color, size, and type of marker to a specific
marker bundle. The aspect source flag (ASF) of MARCOLOR, MARSIZE,
and MARTYPE must be set to 'BUNDLED' before the GDRAW('MARK', . .
. ) function is executed if you want the bundled values to be used
when the marker is drawn.
