.SH NAME
MAPUSR - Called by EZMAP routines that draw the various parts of the map.
The default version does nothing.  A user-written version may be supplied
to change the appearance of the map. Note that this routine is not called
by any of the EZMAPB routines; they call MPCHLN instead.
.SH SYNOPSIS
CALL MAPUSR (IPRT)
.SH DESCRIPTION 
.IP IPRT 12
(input expression, of type INTEGER), if positive, says that a
particular part of the map is about to be drawn, as follows:
.RS 16 
.IP IPRT 6

.IP "7" 6

.RE

If IPRT is negative, then the drawing of the last
part is complete. The absolute value of IPRT will be
one of the above values. Changed quantities should be
restored.
