NAME

6       MAPUSR - Called by EZMAP routines that draw the various parts of the
7       map.  The default version does nothing.  A user-written version may be
8       supplied to change the appearance of the map. Note that this routine is
9       not called by any of the EZMAPB routines; they call MPCHLN instead.

SYNOPSIS

12       CALL MAPUSR (IPRT)
13

DESCRIPTION

15       IPRT        (input expression, of type INTEGER), if positive, says that
16                   a particular part of the map is about to be drawn, as
17                   follows:
18
19                       IPRT  Part of map about to be drawn
20
21                       1     Perimeter.
22
23                       2     Grid.
24
25                       3     Labels.
26
27                       4     Limb lines.
28
29                       5     Continental outlines.
30
31                       6     U.S. state outlines.
32
33                       7     International outlines.
34
35                   If IPRT is negative, then the drawing of the last part is
36                   complete. The absolute value of IPRT will be one of the
37                   above values. Changed quantities should be restored.
38

USAGE

40       EZMAP executes the statement
41
42           CALL MAPUSR (IPRT)
43
44       just before and just after each portion of a map is drawn. The default
45       version of MAPUSR does nothing.
46
47       A user-supplied version of MAPUSR may set/reset the dotting parameter
48       'DL', the DASHCHAR dash pattern, the color index, etc., so as to
49       achieve a desired effect.

EXAMPLES

52       Use the ncargex command to see the following relevant example: mpex08.
53

ACCESS

55       To use MAPUSR, load the NCAR Graphics libraries ncarg, ncarg_gks, and
56       ncarg_c, preferably in that order.
