MAPEOD – Called by the EZMAP routines MAPLOT and MAPBLA. The default version does nothing. A user-written version may be supplied to examine each outline-dataset segment and, perhaps, to delete selected ones. Note that this routine is not called by any of the EZMAPB routines; for the same purpose, they call the routine MPCHLN. Synopsis…
MAPDRW – Draws the complete map described by the current values of the internal parameters of EZMAP.
